deno 1.45.5 (release, x86_64-unknown-linux-gnu)

I'm using wayland, maybe that have to do with it

WAYLAND_DISPLAY="" deno run -A works around the issue

I think it was fixed in 1.46 because I am unable to reproduce it. @littledivy @sigmaSd

Seems to be a Wayland (XWayland) + OpenGL ES issue. I was not able to reproduce this running Wayland (AMD Ryzen gpu)

The back-trace points to internal code in wgpu-hal so I would open an issue there.

@yazan-abdalrahman You are running on Windows. This is a Linux + Wayland bug.
