Current driver does not support Vertex Buffer Object.

[timjim333]

Describe the bug
Starting the OpenVSP graphical app vsp leads to a crash that may be mesa-related - the output is copy-pasted below. Apologies if this is not a WSL bug - I'm unsure if this is related to the being unable to update to the latest mesa

To Reproduce

1. Compile VSP
2. Start XLaunch in Windows
3. run ./vsp

Expected behavior
For the graphical app to launch.

Hello @timjim333

Be sure that the variable LIBGL_ALWAYS_INDIRECT is unset

unset LIBGL_ALWAYS_INDIRECT

Also run glxinfo -B and paste the results here

[timjim333]

@crramirez thanks for the reply! Unsetting LIBGL_ALWAYS_INDIRECT (or setting LIBGL_ALWAYS_INDIRECT=0) before running the progarm solved the issue for vsp - but it seemed to cause glxinfo to crash:

The same thing happens after unset.
Whereas leaving it set:

$ LIBGL_ALWAYS_INDIRECT=0 glxinfo -B

display: 172.22.96.1:0  screen: 0

Was this expected? Thanks!

[crramirez]

Yes this is expected. Now you can use your program with the help of your GPU.

But Fedora Remix should unset this variable automatically. Could you run this script upgrade.sh twice? To see if the em get solved
