This currently fails to compile:

    = note: expected struct `Rc<egui_glow::painter::Context>`
               found struct `Arc<egui_glow::painter::Context

emilk/egui#3598 changed this to use Rc instead of Arc. Smithay's GlowRenderer::with_context passes an &Arc<Context>. Not sure what can be done other than Smithay using Rc, or using a different glow context for egui...

I guess we can try to change this to an Rc in smithay and see if something breaks. Theoretically these contexts are thread-safe, as long as they are not current in multiple threads. So I really don't get why egui made this super unnecessary change. Maybe we should open an issue with them. Ah so this is an issue with glow...

Worst case, if both are not an option, would be to create a shared context for egui...

Seems they have fixed this after the 0.13 release...
grovesNL/glow@edfd08e

sigh

Maybe we can convince egui to change that back, once there is a new glow release. (and then wait for the next egui release? this sucks, maybe we should just temporarily patch this with git dependencies...)

[Drakulix]

Looks like egui will fix this in 0.25 again, so lets wait for that I suppose: emilk/egui#3646

[ids1024]

Annoying, but it it will eventually be fixed in an update, I suppose.

This is now fixed, but needs update in smithay's glow (update to 0.13) for 0.25 and above

PRs welcome :)

We can see if things are working properly with the newly released glow 0.14, once emilk/egui#4833 is released.
