Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-x11 (Nobody) <x11@FreeBSD.org> for maintainer-feedback: Bug 257335: graphics/drm-fbsd13-kmod https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257335 --- Description --- FreeBSD shows heavy artifacting and texture corruption on i915 hardware with mesa's new Gallium3D driver "Crocus". This issue is tracked as a mesa issue here: "Crocus on GM45: texture corruption, bad memory reads and GPU Hangs" ( https://gitlab.freedesktop.org/mesa/mesa/-/issues/5093 ) It has been suggested by a mesa dev, that the cause may be on FreeBSD's side due to "missing some interfaces [...]". That's why I cross-post this as a bug here. TL;DR: With a Laptop with a GM45 chipset, the GMA 4500 MHD iGPU, on the latest kernel, with the latest drm-fbsd13-kmod and the latest mesa-devel, using crocus as the graphics driver to launch any graphical program results in heavy artifacting when a texture is displayed. Attached is a screenshot of the videoplayer "MPV", which shows heavy corruption of the image. Be it Video game or browser, everything shows this corruption, if crocus is used.home | help
