Something that’s been bugging me for a while is the lack of 24-bit visuals when running X in 30-bit colour depth. This causes Steam for Linux to break.
So my question is (mainly to the NVIDIA developers), why aren’t there any 24-bit visuals when running in 30-bit mode? I can kinda understand in the old days, when everything rendered to the same back buffer everything had to use a compatible visual. But surely in a composited desktop, that’s no longer an issue. Is this something that Wayland/Weston solves better? I haven’t taken the plunge to upgrade my F24 install just yet.
This hasn’t really been an issue so far, since I only have a ‘fake’ 10-bpc monitor (Dell 2709W, 8-bpc + FRC) I just leave it in 8-bpc mode, but with HDR and larger colour gamuts becoming more popular (and my next monitor looking to be an ASUS PG27UQ, a real 10-bpc monitor AFAIK) it would be nice to be able to use this feature without breaking random bits of software.
