I have a Nvidia surround setup with triple monitor 7840x1440 with bezel correction. I have made 3 splits 2560x1440.
Since beta 20 when I double click on the title bar or on the maximize button some, not all, programs maximize to full screen only and that is the size of the surround window and not the split.
One of these programs is the windows task manager.
So for now I can not update to beta 21.

This troubleshooting info is from version beta 19. Do you want from beta 21 or is this enough?

Thanks for your reply!

The programs that are not maximizing to spit but to full screen are:
disk management
event viewer
task manager
hwinfo
1password

They work as intended in beta 19, but also not in beta 20 (in that version it all started)!

And I also found out that "Notepad" does maximize to split in all versions, but doesn't resize back to original size.

Thanks and I hope you can find the source of the problem.

yes, it is solved with beta 22, thank you
