Hello

I started having frequent crashes more than a month ago when the Pinephone was on for more than half a day. Recently, I tried to rerun Gnome Clocks, Megapixels, Gnome Control Center, etc after such crashes but in command line and I always obtained a first error message complaining about a failure to allocate memory and a segmentation fault. Is there a known memory leak in Phosh or Mobian? Am I missing something obvious?

I also noticed that (especially with Megapixels, which works again after a reboot) but didn't thought about a memory leak yet - Sounds absolutely possible for me!

When I run gnome-control-center in command line (same with gnome-clocks), I obtain:
DRM_IOCTL_MODE_CREATE_DUMB failed: Cannot allocate memory
Segmentation fault
When I run megapixels in command line, I obtain:
MPCamera: VIDIOC_REQBUFS error 12, Cannot allocate memory
MPCamera: VIDIOC_DQBUFS error 22, Invalid argument

It's a known issue:

Mesa 22.3.5-0.2 fixes this issue. We have to wait.

If the logs tell "DRM_IOCTL_MODE_CREATE_DUMB", then one can either wait for 22.3.6 (currently in sid aka. unstable) or downgrade to 22.3.2-1. The latter can be achieved by browsing snapshot.debian.org, search for the mesa related files ...

I'm still waiting for the fixed version of Mesa. Why does it take so long?

mesa uses/(build?)depends on LLVM version 15 and that got stuck in their transition, holding up mesa's transition.
See https://tracker.debian.org/pkg/mesa for details.

Yeah, lets hope it still makes the cut to Bookworm.

I'm quite certain it will :-)
