Floem apps not responding (Linux, wayland, gnome, nvidia)

[alexjg]

Running cargo run -p widget-gallery (or any of the other examples as far as I can tell) renders a window with the expected contents but the window does not respond to clicks and Gnome pops an ""Unknown" is not responding" prompt after a few seconds.

I'm running a Wayland desktop on Nvidia hardware so I'm quite used to there being glitches, is there some way of building things which I'm missing that would fix this?

[jrmoulton]

It's likely an issue with the winit crate. Do you know if other rust apps that use winit have the same problems?

[alexjg]

I can run various examples from the floem-winit crate locally without issue. Do you have an example of a winit based application I could test though?

Same issue here
