Describe the bug

When trying to run the first program in the tutorial I get this error:

go run main.go X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 149 () Minor opcode of failed request: 4 Serial number of failed request: 239 Current serial number in output stream: 249 exit status 1

How to reproduce

Run this program:

package main

import "cogentcore.org/core/core"

func main() {
	b := core.NewBody()
	core.NewButton(b).SetText("Hello, World!")
	b.RunMainWindow()
}

Example code

The same thing happens when trying to run the clock example in this repo. It does work on my laptop with Ubuntu 24.04, but not my desktop, so I'm not sure if the GPU is causing the problem or it's something else I've installed.

@celer Thank you for reporting this. Can you please paste the output of webgpuinfo and vulkaninfo to help us debug this? Thank you!

FYI, I transferred this issue to cogentcore/core, since that is the repo for the GUI framework, whereas cogentcore/cogent is the repo for our apps made with it; the naming is confusing and we will rename the cogent repo to apps soon.

I went back and made sure I followed the directions on the cogentcore.org for installation to make sure I was following the provided instructions, I still get he same error (after running go clean -modcache)

I did make progress on this, it looks like it was because I was using X11 not Wayland :(
