I have now migrated to Windows 10 which may have helped also but will report back if the issue reoccurs. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#29 Wed, 27 Jun 2018 18:20:16 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#29 DisplayFusion I have some hopefully very good news! I was finally able to reproduce the runaway CPU consistently here, and we're 99.99999% sure that we've gotten it fixed up. We released 9.3 this morning, but then found and fixed the CPU bug, so we've reposted it as DisplayFusionSetup-9.3c.exe. If you've already updated to 9.3, could you re-download it from our website and install it? Double-check that the setup file downloads as DisplayFusionSetup-9.3c.exe.

Thanks! ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#28 Fri, 25 May 2018 13:36:35 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#28 DisplayFusion Yeah, we still haven't been able to track this down. We're going to have another go at it for 9.3. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#27 Fri, 25 May 2018 13:07:16 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#27 DisplayFusion

Thanks Chris! We'll be working on this some more for future betas, so we'll be sure to post an update when we have another build to try.

Thanks!


I notice 9.2 and subsequently, 9.2.1 have been released - should I ignore those for now? ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#26 Tue, 08 May 2018 18:42:50 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#26 DisplayFusion Thanks Chris!

Awesome, glad to hear it!


So I had a CPU spike just now with DF - it lasted about 1-2 mins. I did upgrade to Beta 2 over the weekend. I've added logs if that helps. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#24 Fri, 04 May 2018 12:34:15 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#24 DisplayFusion Awesome, glad to hear it! ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#23 Fri, 04 May 2018 02:14:21 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#23 DisplayFusion So far so good.

Would you be able to try out DisplayFusion 9.2 Beta 1 to see if the issue still exists?


Have installed - will report back in a few days! Thanks. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#21 Fri, 27 Apr 2018 15:39:52 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#21 DisplayFusion Would you be able to try out DisplayFusion 9.2 Beta 1 to see if the issue still exists? ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#20 Thu, 07 Dec 2017 16:32:43 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#20 DisplayFusion A backup wouldn't be a terrible idea, but no need to uninstall first. Just run the 8.1.2 installer and it will overwrite the program files while keeping your settings intact. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#19 Thu, 07 Dec 2017 15:12:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#19 DisplayFusion Thanks - do I need to uninstall DF9 first and then install DF8?

In the meantime can I downgrade back to DF8 as it worked fine there? Are there specific steps I need to follow?

Unfortunately the log doesn't show anything relevant. However, we do have a couple of thoughts on this. They will take some time to investigate, but we'll definitely post an update when we think we've gotten this sorted out.

Thanks for your help with troubleshooting so far! ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#15 Wed, 29 Nov 2017 18:26:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#15 DisplayFusion Ok just happened again around 11am 11/29. This time it seem to start after unlocking my workstation and entering the desktop. L2 log attached. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#14 Tue, 28 Nov 2017 16:52:55 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#14 DisplayFusion Ok will do. It actually happened again today but I didn't have the logging / shortcuts set up.

Is there a way to turn the sounds off when using the keyboard shortcuts? ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#13 Tue, 28 Nov 2017 14:03:55 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#13 DisplayFusion You can try setting key combinations on the "Toggle Multi-Monitor Taskbars" and "Toggle TitleBar Buttons" functions (Settings > Functions) and see if those will disable them when it occurs. If not, can you try enabling L2 logging and send a new log? ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#12 Mon, 27 Nov 2017 19:58:22 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#12 DisplayFusion Is that something I can turn off when the issue occurs? I assume not as DF is pretty unresponsive when the issue occurs.

The problem is this issue doesn't occur very frequently so I'd have to turn off those key features indefinitely which sort of defeats the purpose of using DF. Is there another approach I can take - e.g. next level of logging, perhaps? Thanks. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#11 Mon, 27 Nov 2017 19:50:02 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#11 DisplayFusion Ok, thanks! If you disable the TitleBar Buttons (Settings > Functions) or Multi-Monitor Taskbar (Settings > Taskbar), does this still occur? ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#10 Mon, 27 Nov 2017 19:38:30 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#10 DisplayFusion No resolution/Aero changes. Laptop was docked whole time and I was just running standard Office 2016 apps mainly. I noticed the slow down when I came to make a VoIP call using Cisco Jabber as DTMF tones were getting delayed and then noticed CPU usage spike.

Interestingly though when I killed the DF process and restarted it, DF started consuming 70-80% CPU again so had to kill it again. On the 3rd attempt it was ok. ]]> RE: CPU Spikes with DF9 https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#9 Mon, 27 Nov 2017 17:55:09 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-spikes-with-df9/?ID=7eff5b77-15bb-4160-8b41-07b249fd149b#9 DisplayFusion Thanks!

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • The next time it occurs, note the time so we'll know where to check in the log file
  • Send us the DisplayFusion.log and DebugInfo.html files (can be found by clicking the Open Log button on the Troubleshooting tab)
  • Disable debug logging after sending the log
