1.8.07 is the latest version without an issue for me

[Rowsol]

2.0.05 makes the screen black if I change resolution (game still working in background but no picture). If I change it with the .ini it works fine. The real issue for me is this second one.
both 2.0.05 and 1.8.10 have a 2 second delay to maximize the game window after alt-tab. 1.8.07 doesn't have this issue. Here's the exact steps I took.

Reverted Nvidia control panel settings to default.
Exited out of Afterburner. (no other programs in the background)
Deleted the .ini.
Started the game and changed the resolution to my panel (1920x1080).
Started a new game and alt-tabbed.

Only 1.8.07 restores the game window properly, the other ones have an annoying 2 second delay. I have only tried these 3 versions since they are posted as non-beta releases but I can try some of the git builds if you want me to. I hope this was helpful. Here's my specs.

intel 3258 cpu
650 ti boost gpu (driver:347.25)
4gb ram
mx 100 ssd
win 7 pro 64 bit

I think this is the problem:

Unfortunately it hasn't been fixed yet in ZDoom so at the moment all I can do is wait.
