Log from running Cossacks 2

When I go to the desktop when I'm in map campaign in Cossacks 2 Battle for
Europe(gog version 1.3) then when I back the screen is broke at the bottom and
doesn't show any buttons until I go to battle.

In battle when I use ALT-TAB, then map becomes transparent.

Very rarely Cossacks crash when I use ALT-TAB and show this errors
002b:err:x11settings:X11DRV_ChangeDisplaySettingsEx No matching mode found:
width=160 height=24 bpp=16 (XRandR 1.2)

This happens also on my laptop with Intel HD 3000(Mesa 19.3) but also on
computer with GTX 970(Nvidia 440)

This isn't recent bug because this happens to me also 1/2 years ago
