"Pitch black" rendering

update: problems only with SDL_VIDEODRIVER=wayland

Works for me!

That said, you need to provide more information.
For example, if you say this happens with latest git, what is the last commit that worked?
If you can't change the contrast in the UI, did you try changing it in the console?

Trying with wayland, I can see the image is noticeably darker (looks like a color space issue - color values are not interpreted as sRGB, as they should), but I wouldn't call it "pitch black".
I'm not sure entirely what's going on; I believe the framebuffer setup used to work (see other wayland-related discussions here), but otoh, some suspicious validation issues relating to the framebuffer format are reported.
Maybe fixing them would also fix the color space issues.

For the time being, if you can use an SDL video driver other than wayland, this may work better.

For me it is best observed running demo demo1

The issues I could reproduce went away after a software update (essentially, Fedora 38 to 39), so this may actually be something that doesn't need fixing in Q2RTX (or may not even be fixable there).
