GLMakie displays false colours in WSL2

[aris]

Hello everyone,

In WSL2 ubuntu, GLMakie gives me weird colours for some reason.
For example,

using GLMakie 
lines(rand(10))

results in:

If I save the plot, the colours in the .png image are fine, its just the display window that’s acting funny.

The following info might help:

This is a know issue with Mesa falling back to software rasterization via llvmpipe:

Wrong color buffers for GLMakie on Mesa llvmpipe

The issue contains some pointers on how to get hardware acceleration going on WSL.

Thanks for the reply Simon.

I tried following the advice in the link you provided but it doesnt seem to work.

glxinfo | grep renderer

    GLX_MESA_copy_sub_buffer, GLX_MESA_gl_interop, GLX_MESA_query_renderer,
    GLX_MESA_copy_sub_buffer, GLX_MESA_query_renderer, GLX_SGIS_multisample,
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: llvmpipe (LLVM 19.1.1, 256 bits)

Could it perhaps be because I am running it on Intel integrated graphics instead of an actual gpu?

got this, too. I’m also using an Intel integrated graphics:

(base) ➜  dev glxinfo | grep renderer
    GLX_MESA_copy_sub_buffer, GLX_MESA_query_renderer, GLX_MESA_swap_control, 
    GLX_MESA_copy_sub_buffer, GLX_MESA_query_renderer, GLX_OML_swap_method, 
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: llvmpipe (LLVM 15.0.7, 256 bits)

@aris

integrated graphics instead of an actual gpu?

Integrated gpus are actual GPUs
From my experience intel has the worst drivers of all vendors…
You’ll need to google/chat to see if there’s a solution.

It can always be a little bit of an adventure to get GPU hardware acceleration fully working on linux/wsl.
I recently had success with OpenSuse tumbleweed for WSL, which seems to have fixes earlier, but not sure if i was just lucky

Got it, I’ll have a go at it once I find some time.

After some rounds with Gemini, there might be incompatiblity of my current GPU from Ubuntu system, which needs a lot of work to figure out I think..
