Ok.

Looks under Wayland it does not work. I think on Wayland (KWIN+WAYLAND) it
works, because I use proton-ge probably. I attached other logs, but now from
Wayland. On X11 there is only black screen and on Wayland, image is only on
part of screen (rest screen is black; game rendered image does not render on
full screen).

I also debug xrandr, x11, etc. - instead of GDI.
