NetBSD netbsd10 10.99.14 NetBSD 10.99.14 (MYKERNEL) #1: Thu May 15 17:57:27 MSK 2025  guest@slax:/mnt/sdb5/home/guest/amd64-obj/sys/arch/amd64/compile/MYKERNEL amd64

>Description:
I updated my 10.1 install to self-compiled 10.99.14 with DAGNOSTIC enabled (so it avoids crash on startx) and then updated userspace from My 15 binary snapshot.

Now I have:
OpenGL renderer string: AMD Radeon RX 550 / 550 Series (POLARIS12, DRM 3.36.0, 10.99.14, LLVM 13.0.0)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 21.3.7
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

but firefox in this case launch (under fluxbox WM) as just blak rectangle! I can blindly poke menu with mouse cursor, and exit it.

If i launch as LIBGL_ALWAYS_SOFTWARE=1 firefox

it at least works enough for sending this bugreport

Launching firefox from another console spews this:

netbsd10# DISPLAY=":0" firefox

If they do, bad things may happen!

>How-To-Repeat:
Install Netbsd amd64 -current on machine with Polaris12 GPU
Make sure user  does have DRI/ hw accelerated  opengl

Install firefox by using pkgin

Try to use it.
>Fix:
LIBGL_ALWAYS_SOFTWARE=1 before launching firefox
