firefox in VNC: firefox.core

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

For a couple days/weeks now, whenever I start firefox
86.0.1/NetBSD-9.99.81/amd64 in a vnc window, I see:

Crash Annotation GraphicsCriticalError: [0][GFX1-]: No GPUs detected via PCI (t=0.228558) [GFX-1]: No GPUs detected via PCI
Crash Annotation Graphicscriticalerror: [0][GFX1-]: No GPUs detected via PCI (t=0.228558) [1][GFX1-]: glxtest: process failed (received signal 11) (t=0.228639) [GFX1-]: glxtest: process failed (received signal 11)

Except for that warning (and the core dump), firefox seems to work fine.

The firefox.core backtrace looks like this:

Core was generated by `firefox'.
Program terminated with signal SIGSEGV, Segmentation fault.

Is this a bug in Mesa without acceleration?
