Game alt+tab issues

Hi all,

I'm having issues when playing various games in non-windowed mode with resolutions such as 800x600, 1280x720, etc.
This happens for games such as Counter-strike:Global Offensive & Starcraft2.

1. The alt+tab from the game and to the game a very slow (5+ seconds), while they aren't slow when displayfusion is stopped (just tested).
2. When alt+tab tabbing, it seems that displayfusion keeps crashing and restarting and during that period ot removes/adds the taskbar a couple of times on the second monitor.

Could you attach a debug log? Here are the steps:

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • Reproduce the issue and 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

Thanks!

Apologies for the delay.. was on vacation :)

I've reproduced the issue - ~21:32 & 21:35.

File is attached.
It only happens when the game is in fullscreen. Also the alt+tab is quite slow. In windowed mode it's fine, but windowed mode doesn't support resolutions different that the display.

No worries! If you create a rule on the DisplayFusion Settings > Compatibility tab for the game and enable the "Disable multi-monitor taskbar" option in the rule, does that resolve the issue?

No such option.

Ah sorry, I mean the "Disable DisplayFusion taskbars while this application is running" option.

Ok.. so I tested it.. and indeed this solves the issue, but since the game is alt+tabbed most of the time.. it's not really a solution.

On the Settings > Taskbar tab, is the "Allow taskbar reloading while full screen..." option enabled?

Hi :)

Yes, it's enabled.

Ok, if you disable that (and remove the Compatibility rule), does it make any difference?

Yep, that does seem to have resolved it partially.
When I alt+tab into the game it seems fine.
When I alt+tab out of the game the taskbar stops/crashes and reloads.

Edit: Hmm.. although this doesn't happen constantly.

Is the game set to a different resolution than the desktop?

It is, yes.
It's a non standard resolution -> 1280x720 or 1680x1050, while the monitor/desktop is at 1920x1080.

Ok, that makes sense then. DisplayFusion will reload the taskbar when the resolution changes as it has to remove/re-add the taskbar to update the work area with Windows.
