DPI scaling issue with Tiberian Sun

[Crimsonum]

I've had this issue for a while where, when using high DPI scaling on Windows, the game sometimes won't go fullscreen, instead it just minimizes. I have a UHD display so I use 150% DPI scaling by default, and run the game on fullscreen mode, usually in 1280x720 resolution (game resolution doesn't affect the issue though).

This bug happens in "sessions": when the problem appears, it usually persists until I reboot Windows, or if I revert to no (100%) scaling. It doesn't occur during every Windows session though, for some reason.

try this. Or something in compatibility DPI app options.

Can't reproduce+stale

I did not notice the replies before. App-specific DPI settings don't help, I've tried it. Only reliable way is to change the Windows DPI to 100 % but I obviously can't use that all the time.

Nothing unusual in it (looks about the same on my end), just that it doesn't minimize here.

I added some more logging trying to print out the name of the window that stole the focus:

This may have been fixed in 5.6.0.0 as I haven't experienced it since.
