Panic on mouseover

@zesterer Please confirm if the issue is still present. I have tested multi_window on x11 and it seems to work correctly. Glutin (and by extension winit) has been updated massively.

If it still causes an issue, please provide me with your distribution, distro version, version of xorg (x11), desktop environment/window manager, etc. and I will attempt to reproduce.

@LoganDark I can confirm that this issue still exists on 0.7.0.

You can see it when running any of the examples from the refactor on https://www.github.com/zesterer/euc branch (requires nightly).

My desktop environment is Budgie on Arch Linux.

My xorg version is:

X.Org X Server 1.20.10
X Protocol Version 11, Revision 0

@LoganDark I can confirm that this issue still exists on 0.7.0.

I'm talking about 0.8.0, which is the huge overhaul I did in #5.

X.Org X Server 1.20.10

I'll set it up in a VM and see if I can reproduce.

I have successfully reproduced your issue using my local Arch install, by running the euc teapot example. Seems to not be Budgie-specific.

It looks like an issue caused by winit being outdated. mini_gl_fb 0.8.0 should fix this by updating winit. However, it's not yet published to crates.io. Bug @dxenonb for that...

[LoganDark]

Yeah, this is a problem with winit: https://stackoverflow.com/a/65261408
