Very high CPU usage on Wayland

[vladh]

Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

Running the hello world example on Wayland results in 170% CPU usage. Running the same example on X11 results in ~0% CPU usage. Running wgpu's hello_triangle also results in ~0% CPU usage.

I've tried some basic profiling with samply but have been unsuccessful as my call stack is full of radeonsi_dri.so calls in the first 400ms after launch, and is then empty, so my profiling must be missing some calls.

What is the expected behavior?

I would expect very low CPU usage on Wayland when running the hello world example.
