we’re experiencing degraded Performance in the Editor on Ubuntu (multiple Versions) on Unity3D 2022.2.0f.
Even when not in Play mode (Profiler in Edit Mode) there are Lag spikes where the Editor hogs CPU like crazy. The bottleneck seems to be somewhere in the refreshing of the UI, when I follow the profiling trace. (Will add screenshots later when booted back into a representative OS).
Every couple of seconds the Editor seems to hang, overall load on the System rises to 6 and above, showing 3 Unity Processes requesting 100%+ CPU cycles. This seems to be worse when the Project Settings Tab is active vs. the Inspector Tab. The lag / freeze eats inputs, which makes the Editor pretty much unusable. Activating Play Mode increases the problem of course.
The problem persists through multiple Projects (even a completely empty one, URP and Non URP), over multiple OS versions (LTS and non LTS), and does not happen on 2022.1.2X on the same machines / OS combinations, which is the current workaround for us.
Has anyone else experienced this?
[Edit: Narrowed down unaffected version from 2021 to 2022.1]
