Title:
hwacc build crashes on direct scanout.
Status in
Unfortunately, removing the --enable-hardware-overlays flag does not
help.
Still crashes when full screen:
Chromium111.0.5563.19 (Official Build) snap (64-bit)
Revision

JavaScript V8 11.1.2
Public bug reported:
This pertains to the HWACC branches of the chromium snap.
When launched full-screen on an Intel iGPU, the hardware overlay use
will result in a core dump.
This could be related to direct-scanout and overlay planes?
To reproduce:
$ chromium --start-fullscreen
OS: Ubuntu 22
Note that when logging into build VM after building the chromium-hwacc
snap:

And not the expected
/snap/gnome-3-38-2004/current/usr/lib/x86_64-linux-gnu/dri
this value is from here,
Hard-coding the dri directory to point to the snap's dri dir fixes this,

I have reproduced this with a chromium that I built manually, from source, not

I also experienced this problem, and upgrading xserver-xorg-core and
