Package: libglx-mesa0 Version: 24.3.4-3 Severity: normal Debian Trixie. After upgrading the following packages
libglx-mesa0:amd64 (24.2.8-1, 24.3.4-3), libgbm1:amd64 (24.2.8-1, 24.3.4-3), libgl1-mesa-dri:amd64 (24.2.8-1, 24.3.4-3), libegl-mesa0:amd64 (24.2.8-1, 24.3.4-3) cannot use mpv with vo=gpu on a Nehalem Intel iGPU machine, so video playback is terribly slow. Bisected to mesa 24.3.0-1. Tried various additional mesa and mpv debug env vars, but no exact issue still. Below are mpv logs from `mpv --msg-level=all=v video.mp4`. Maybe it is really a mpv thing. I don't get how there is [vo/gpu/drm] part after it failed to use OpenGL 4.5 in the broken version. There is no attempt to use OpenGL 4.5 on my ancient machine with 24.2.8-1. Relevant part of broken mpv logs: ``` [vo/gpu/x11] Current display FPS: 60.031185 [vo/gpu/opengl] EGL_VERSION=1.5 [vo/gpu/opengl] EGL_VENDOR=Mesa Project [vo/gpu/opengl] EGL_CLIENT_APIS=OpenGL OpenGL_ES [vo/gpu/opengl] Trying to create Desktop OpenGL context.
