Created attachment 1743722 [details] example Description of problem: videos look pixelated and/or over sharpened when hw acceleration is enabled. I've provided you with an "example" picture of what it looks like with hw acceleration enabled (left) and disabled (right). Version-Release number of selected component (if applicable): gnome-shell-3.38.2-5.fc33.x86_64 wayland-1.18.0-1.fc33 vlc-3.0.12-1.fc33.x86_64 mesa-20.3.2-1.fc33 How reproducible: always. Steps to Reproduce: 1. enable hw acceleration. 2. play a video. Actual results: videos look "pixelated", or over sharpened with hw enabled. Expected results: flawless video w/wo hw acceleration. This is the closest thing I've found, while searching for an answer online, though most likely not related: https://bbs.archlinux.org/viewtopic.php?id=261471 x86_64, PRIME Z270-A, i5-7600K, 16GB DDR4, AMD RX 580 8GB (MESA 20.3.2) & 970 EVO M.2.
As it turns out, it was a problem with VA-API, but disabling HW rendering or using VDPAU solved it, though I'm not sure what to make of it.
Mesa <20.3 had a bug (https://gitlab.freedesktop.org/mesa/mesa/-/issues/1193) that caused VA-API not to work at all in VLC when using the AMD driver.
For what it's worth, I can't repro this, though my environment is somewhat different: Hardware: RX 5500 XT Software: - KDE 5.20.4/Qt 5.15.2 - X11 - vlc-3.0.12-1.fc33 - mesa-20.3.2-1.fc33 Re: VDPAU - I was under the impression that that was tied to X11 and didn't work under Wayland - can you confirm that it's working in VLC and not falling back to software rendering? https://github.com/mpv-player/mpv/issues/6968
Thanks for pointing that out, it looks to be falling back to software and I noticed the same behaviour when selecting VA-API (drm).
