I'm concerned the rationale here may still overlap bug 2143073 in a confusing way:
> This is NOT the ShmemHugePages leak reported at the top of #2143073. There the > shmem is orphaned in pagecache with no process accounting for it. Here the > memory is attributed to gnome-shell's cgroup and the objects that grow are > dma-bufs listed in /sys/kernel/debug/dma_buf/bufinfo, released again when the > session leaves power saving. That matches upstream #4101 (detached_onscreens > never cleared during power saving). Blame for bug 2143073 lies entirely within the gnome-shell process, and it is released when unlocking the screen, which can be confused for "when the session leaves power saving". -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2167374 Title: gnome-shell leaks scanout dma-bufs while locked (fixed in mutter 50.5) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2167374/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
