Jack_Hell: Overlay (Settings/Game features/in-game features/Overlay) is disabled and this does not affect this issue. Not all games have this problem, but half of my games do.
TheDudeLebowski: Things to try:
*set your display to 100% (Display Properties after right-clicking the desktop)
*disable extra monitors (Display Properties again)
*disable auto-hiding the taskbar
I've had the same issue happen to me two-three times, but it was random, and I don't know what may have caused it.
I can turn off automatic hiding of the taskbar (this is the only thing I have listed), but this solution is a compromise, I hope the developers will fix this bug .... And yet they will add the ability to manually edit the genre graph to any game)))
Martek: Happens to me on occasion. Just one of those things.
While some of the noted things to try might fix it; for me, I'd rather just click on the game window to bring it into focus than to make some of the suggested changes. I don't want to disable auto-hiding, etc. So, I live with it.
I agree with you, I like a clean desktop. So I'll try to disable hiding the taskbar, but in the end I will return this feature anyway.
Thank you all for trying to help and advise. Peace for everyone!
