App window is brought to foreground whenever Context::request_repaint is called

[Barugon]

egui version 0.24.0

Describe the bug
In addition to what the title says, even without calling Context::request_repaint, the window remains on top when I switch to another app.

To Reproduce

1. Build and runt the attached project. It will issue a Context::request_repaint every second.
2. Switch to another app and note that this app's window will be moved to the foreground.

Even if Context::request_repaint is not deliberately called, moving your mouse over any exposed part of the window will bring it to the front.

Expected behavior
Context::request_repaint should not effect the desktop window order.

Thanks for the report! I cannot reproduce on Mac, so I suspect this is a bug specific to Linux/Wayland.

Is this a new bug for 0.24?

Does it still happen if you use the "wgpu" feature of eframe?
If it is glow only, I wonder if it could be because of the make_current call 🤔

Does it only happen when waking from a background thread, or does it happen with Context::request_repaint_after too?

I can confirm that this bug is new in 0.24 and happens also on Linux without using Wayland. I use Context::request_repaint_after in my application.

Yes.

If I try to build with the "wgpu" feature then I get this error:

the package `wgpu` depends on `web-sys`, with features: `GpuComputePassTimestampWrite` but `web-sys` does not have these features.

[edit] I don't know why web-sys needs to be pulled in for a non-wasm project.

Very weird, but should be fixed with RUSTFLAGS='--cfg=web_sys_unstable_apis'

Can't reproduce on hyprland after applying fix for #3628, this might be a duplicate. Could you try disabling x11 feature and trying again?

Potential fix: #3643

#3643 fixes the issue for me.
