error on windows 11

i am getting the following errors. Any advice?

❯ wezterm
09:21:04.426  ERROR  wgpu::backend::direct > Error in Adapter::request_device: Limit 'max_compute_workgroups_per_dimension' value 65535 is better than allowed 0

Hi @azinsharaf
I'm not able to recreate the issue on my end.

Have you tried running the config with one of the nightly builds of Wezterm?
Cuz I know the current stable release has some issues that are fixed in the nightly builds

Hey @azinsharaf
The errors you're getting are mentioned in this wezterm issue

And it seems to be tied with an issue that the wgpu crate has when rendering on some AMD cards.
WezTerm relies on this crate for rendering if the front_end option is set to WebGpu.

The latest nightly build uses a newer version of the crate which may have addressed this issue.
So if the nightly build can't run this config I think your best shot would in setting the front_end option to OpenGL in the file ./config/appearance.lua

wezterm-config/config/appearance.lua

Lines 4 to 9 in 961570c

    
           return { 
        
              animation_fps = 60, 
        
              max_fps = 60, 
        
              front_end = 'WebGpu', 
        
              webgpu_power_preference = 'HighPerformance',

To:

   front_end = 'OpenGL'

Hope this helps 😊

yes, changing to OpenGL fixed it. quick question: does it mean that wezterm won't use gpu if we set it to opengl?
thanks!

Not really, wezterm will still use the GPU.

My understanding is that OpenGL is like a cross-platform abstraction layer to make it easier to work with the GPUs.
While the wgpu crate is more of a bare-metal approach.

OpenGL is technically the slower of the two options but the difference isn't even noticeable.
I just have it set to WebGpu cuz it's the shiny new toy 😅

	return {
	animation_fps = 60,
	max_fps = 60,
	front_end = 'WebGpu',
	webgpu_power_preference = 'HighPerformance',
