[Pkg-tigervnc-devel] Bug#1134461: tigervnc-xorg-extension causes random xorg crashes on PC with Intel N100 CPU

[stefan]

Package: tigervnc-xorg-extension
Version: 1.15.0+dfsg-2
Severity: normal
X-Debbugs-Cc: debian-amd64 at lists.debian.org
User: debian-amd64 at lists.debian.org
Usertags: amd64

Dear Maintainer,

xorg crashes randomly (every few hours) after update from Debian 12 to 13. That
could be fixed by downgrading the package `tigervnc-xorg-extension` from
1.15.0+dfsg-2 to 1.12.0+dfsg-8 (from Debian 12). That is why I consider this
package as responsible.

What I found out so far:

1. I'm running the same installation on many PCs. The issue only occurred on
two machines with Intel N100 CPU/SoC: a Shuttle "DL30N" mini PC a Asrock
"N100DC-ITX" mainboard. I did not noticed the problem on AMD CPUs.
I did not tested other Intel CPU's (than the two N100 machines).

2. The problem occurs with both the (old ?) intel xorg driver and the kms
driver

3. Xorg crashes silently. I could not find anything in syslog, the xorg log and
`~/.xsession-errors`
A compressed xorg logfile with high verbosity level is attached.

Regards Stefan
