Tested jammy with crocus on an i5-4300U, both 22.0.5-0ubuntu0.1 and 22.0.5-0ubuntu0.2
gnome-shell's RSS grows but seems to plateau similarly with both. Based on upstream's comments, I started counting i915.gem instances in /proc/PID/smaps and found that both 22.0.5-0ubuntu0.1 and 22.0.5-0ubuntu0.2 seem to leak them equally. Never reached the point of crashing but the evidence is that mesa 22.0.5-0ubuntu0.2 makes gnome- shell leak almost as much as 22.0.5-0ubuntu0.1 ... That said, I expect most graphics leaks to be hardware independent and the fault of gnome- shell/mutter, not mesa. Looking at the upstream fix again I realize it's not fixing all the leaks that's important here, but avoiding crashes when they occur. And for that we are missing the correct patch: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/17615/diffs It's not in mesa_22.0.5-0ubuntu0.2.diff.gz ** Tags removed: verification-needed-jammy ** Tags added: verification-failed-jammy -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1972977 Title: gnome-shell crashed (out of memory) with SIGSEGV in crocus_begin_query() from crocus_begin_query() from crocus_end_query() from crocus_end_query() from tc_call_end_query() Status in Mesa: Fix Released Status in mesa package in Ubuntu: Fix Released Status in mesa source package in Jammy: Fix Committed Bug description: [Impact] Gnome-shell is crashing on older gen Intel hw due to a memory leak.
