Thanks! If you disable Window Snapping on the DisplayFusion Settings > Window Snapping tab, does that make any difference?


My immediate impression is that yes, it does seem to make an improvement, and Window snapping is not a feature I'll miss. Let me shake it down for a couple of days and see if the problem returns.

Thanks! ]]> RE: DisplayFusion & Window Dragging - Slows and Stutters Over Time https://www.displayfusion.com/Discussions/View/displayfusion-window-dragging-slows-and-stutters-over-time/?ID=41cb2129-b615-4696-8610-5b7d3b684f60#6 Tue, 04 Aug 2020 19:44:31 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-window-dragging-slows-and-stutters-over-time/?ID=41cb2129-b615-4696-8610-5b7d3b684f60#6 DisplayFusion Thanks!

It was happening shortly after I received notification of your message.

As before, exiting and restarting DF fixed the problem ... at least for a while.

Would you be able to attach a debug log?

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • The next time the issue occurs, note the time so we'll know where to check in the log file
  • Click the "Export Info to File" button on the Settings > Troubleshooting tab
  • Reply with the file attached
  • Disable debug logging after sending the log

Is it all windows that have that issue, or only specific applications?

It seems to be any application. I grab one to move it, and it hiccups and jerks a bit, and sometimes triggers the "shake to minimize" feature of Windows. But stopping/starting DF brings it back to normal for some unpredictable period of time.

My hardware isn't exactly state of the art; it's a Lenovo T460p with discrete graphics, a 27" Lenovo X1 4K display and 2 Dell 1920 x 1280 displays flanking it. ]]> RE: DisplayFusion & Window Dragging - Slows and Stutters Over Time https://www.displayfusion.com/Discussions/View/displayfusion-window-dragging-slows-and-stutters-over-time/?ID=41cb2129-b615-4696-8610-5b7d3b684f60#2 Wed, 29 Jul 2020 17:19:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-window-dragging-slows-and-stutters-over-time/?ID=41cb2129-b615-4696-8610-5b7d3b684f60#2 DisplayFusion Is it all windows that have that issue, or only specific applications? ]]> DisplayFusion & Window Dragging - Slows and Stutters Over Time https://www.displayfusion.com/Discussions/View/displayfusion-window-dragging-slows-and-stutters-over-time/?ID=41cb2129-b615-4696-8610-5b7d3b684f60 Mon, 27 Jul 2020 20:25:35 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-window-dragging-slows-and-stutters-over-time/?ID=41cb2129-b615-4696-8610-5b7d3b684f60 DisplayFusion There's some sort of issue with running DF over a period of time. Dragging a window will become slow and jerky, to the point where Windows thinks I'm shaking the mouse to "minimize all but current window." If I exit DF and restart it, it's OK for a while. Days, sometimes weeks. But there's something off and it would be nice to to have it happen ...

Overall my configuration is pretty basic; I'm running 3 displays (4K in the middle flanked by two @ 1920x1280) with corner cursor snag prevention (or whatever it's called) enabled. ]]>
