High CPU usage when doing camera orbit.

It's interesting that we don't notice that on Windows. The CPU usage indeed increases on mouse movement, but far away to make the CPU reach 100%.

In the fractional scaling added to Ubuntu 20.04 (link) they supposedly improved this:

There's also improved performance. There's lower CPU usage for window and overview animations, JavaScript execution, mouse movement and window movement (which also has lower latency now).
