Sample doesn't work on Edge about egui HOT 3 CLOSED

Thanks for the report!

I don't have a Windows machine, so it is hard for me to debug. Does the developer console say anything helpful?

from egui.

It says:

RuntimeError: unreachable

So I guess something unreachable in webgl is in fact reached? Sorry, web stuff is very much outside my wheel house so I'm not sure how to debug stuff like this.

Update: this went away after restarting Edge. So my hypothesis is that something in my browser session (probably up for days) caused a GPU hang in the past, which (I believe) causes edge to disable using the GPU from then on. Which in turn would disable things like WebGL.

So I think this is really more of "show error message if webgl fails to load" rather than an actual persistent issue on Edge.
