Thank you for reporting back! > Sorry for missing pieces of info in my original report.
Don't worry, you even used Apport and provided many useful details. Apparently, Apport doesn't submit enough information if snapd is its target. Can you please run apport-collect -p chromium-browser 2004532 I think that will give us more information, I'm particularly interested in dmesg at least. The journal output after you launch Chromium could also be useful, say: journalctl -r | head -n 300 > journal.log My apologies for not having asked all that at once. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/2004532 Title: Hardware acceleration broken for amdgpu/mesa in snap Status in chromium-browser package in Ubuntu: New Status in firefox package in Ubuntu: New Status in snapd package in Ubuntu: New Bug description: Snap packages which use hardware accelerated graphics are broken after the last routine system upgrade via apt. My system is using AMD Radeon RX 5500 XT graphics card from ASUS, with stock amdgpu kernel drivers. Two snap packages which are now unusable are Mozilla Firefox and Chromium browsers. Both display animated speckled color garbage inside their windows, overlayed with the correct image. Disabling hardware acceleration in the settings for the snap version of Firefox fixed it. Also, Firefox version installed from the original Mozilla tarball into /opt/ works just fine with the acceleration enabled on the same system, as well as glmark2 benchmark. Looks like the issue is only affecting snap packages. $ snap list firefox chromium Name Version Rev Tracking Publisher Notes chromium 109.0.5414.119 2295 latest/stable canonical✓ - firefox 109.0.1-1 2311 latest/stable mozilla✓ - $ dpkg -l snapd|grep ^ii ii snapd 2.58+22.10 amd64 Daemon and tooling that enable snap packages $ dpkg -l mesa\* | grep ^ii ii mesa-utils 8.5.0-1 amd64 Miscellaneous Mesa utilities -- symlinks ii mesa-utils-bin:amd64 8.5.0-1 amd64 Miscellaneous Mesa utilities -- native applications ii mesa-va-drivers:amd64 22.2.5-0ubuntu0.1 amd64 Mesa VA-API video acceleration drivers ii mesa-vdpau-drivers:amd64 22.2.5-0ubuntu0.1 amd64 Mesa VDPAU video acceleration drivers ii mesa-vulkan-drivers:amd64 22.2.5-0ubuntu0.1 amd64 Mesa Vulkan graphics drivers $ lsb_release -a No LSB modules are available.
