Silksong HDR on
A problem is that the screenshots captured by Spectacle don't really show what I'm seeing from in-game ~ HDR makes colours a lot more muted, which Spectable isn't picking up on. Or maybe that's a Gwenview issue... dunno. But looking at different areas, colours aren't popping and searing my eyes like they used to. Not sure what changed... Can't bisect back further than https://invent.kde.org/plasma/kwin/-/commit/08a945439d4f631449400935ca046d6263940811 which won't build due to needed changes, but still broken on that commit too. Can reproduce in Monster Hunter Wilds too ~ using native HDR this time. Created attachment 185506 [details]

KWin info: https://invent.kde.org/-/snippets/3560 Can reproduce the same results in 6.4.5 ~ can't get a screenshot, though, as Spectacle is broken there for some reason: Operating System: CachyOS Linux KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.10.0 Kernel Version: 6.17.1-1-cachyos-bore (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7800X3D 8-Core Processor Memory: 32 GiB of RAM (30.2 GiB usable) Graphics Processor 1: AMD Radeon RX 7900 XTX Graphics Processor 2: AMD Radeon Graphics Manufacturer: ASRock Product Name: X670E Pro RS Created attachment 185638 [details]

I can't confirm that, HDR games still look fine here. If you compile and run https://invent.kde.org/zamundaaa/colortest, does BT2020+gamma 2.2 look more or less saturated than just sRGB?

Yes ~ the colours look slightly more intense by comparison. Because stable KWin doesn't seem to change anything, can I ask what kernel version you're testing with? Also what Mesa version and hardware? Maybe even firmware version? Wondering if there's some weird bug there somewhere screwing things up. The colour pallettes change, but the image's colour do not. But if I change the nits slider, the higher it goes, the darker the image gets shadow and highlights-wise. That doesn't seem like it should be happening... Created attachment 185753 [details]

I am an idiot... if the colours are borked on my system, why would they show up in screenshots? Sigh.

Another thing I've just considered... my libdisplay version is 0.3.0, per a recent update. Not sure whether that could be having an effect. Unfortunately, the same issue appears to plague Gamescope tty session, so this isn't a KWin bug, happily. Sorry for the useless bug report ~ chasing ghosts is an annoying game... |
