We have been digging through the log file and trying to replicate the issue but so far we're unable to. We're happy to continue digging and we are up to Beta 4 now which is worth trying to see if it helps. Thanks!
When utilising Alt+Tab and in a fullscreen borderless game like Escape from Tarkov and League of Legends, pressing alt+tab will instantly close the dialogue. This does not occur in Overwatch.
When holding Alt down, it will continously flicker. Sometimes when spam clicking to alt tab it will randomly get fixed. I have attached a video of what happens when holding down alt using Current Monitor + Current Windows.
So far, the only configuration in which this does not occur is Show on All Monitors, Show Current Windows Only in which it will close the first time, but will work on the second attempt and beyond but this behaviour resets when you tab out. In this mode however, you cannot change the selected window with Tab.
Sometimes, I have been able to fix this by spamming the alt+tab or by changing to fullscreen and back but it is not replicable nor does it happen often.
This behaviour happens on 12.0.2 and 12.1 Beta v3
I tested this with League of Legends here but I can't reproduce it. Could you send me a debug log? Here are the steps:
I start to alt tab at about 17:13:20 and it goes almost until the end of the log
I will note that previously it was working fine and I had to restart in order to recreate the bug again

Could you set the "Log Level for Hooks" advanced setting to "1", and then reboot and grab a new log?
Alt tabbing at about 18:32:05
HKCU\Software\Binary Fortress Software\DisplayFusion\LogDebugLevelHooks REG_SZ is set to 1 and I did restart my computer. This time I could not recreate it immediately in League of Legends so I used Escape From Tarkov

It doesn't look like that log has any lines from the advanced setting, could you reboot and grab a fresh log?
Initial log at 14:53:46
Second log at 17:59:23
Not sure if these would have anything changed, I've had the LogDebugLevelHooks set to 1 for that entire duration, and have rebooted before starting each log.
Are the advanced settings supposed to be configured like in my image?

Yep it looks like you have it set correctly, I'll pass it over to our developers to have another look at and keep you posted.
Thanks!
I'm sorry for the delay, things are quite busy during the summer but we still have this on the list for testing next week. Thanks!
Hello, would you be able to give this new 12.1.2 Beta 1 a try? If you're still having the same issue can you submit another log just like before with the hook log level set to 1? Thanks!
I believe after the update, it is much less prevalent in League of Legends and I may have seen it only occur once.
I was able to replicate it in Escape From Tarkov, but not immediately after a restart.
Since this is such a sporadic issue, I might just do a fresh windows 11 install some time in the future.
