Package: libgl1-mesa-dri Version: 25.0.7-2+deb13u1 Severity: important Tags: upstream
Dear Maintainer, CONTEXT ======= I upgraded this machine from Debian 11 to Debian 12 to Debian 13. On Debian 12 I do not know whether I was running Xorg or Wayland, but everything seemed to work fine, which is why I went ahead and upgraded to 13. Debian 13 gave me a Wayland session by default, and that is when I started having trouble with this graphics card. WHAT I OBSERVE ============== On a GeForce 210 (GT218, Tesla) using nouveau, the kernel logs PGRAPH faults attributed to gst-plugin-scan every time the GStreamer plugin registry is rebuilt. This happens a few seconds into every session since the upgrade. No application prints anything; I only see it in dmesg. I do not know which plugin or which Mesa code path is responsible. In a Wayland session my whole session freezes when this happens, which I have reported separately as Debian bug #1147096. I cannot say whether the two are actually related: the faults below also occur under Xorg, where nothing bad happens.
