Question Unity Editor Very slow and unusable on Debian (testing)

I recently installed unity editor on a debian linux machine.

But it is totally unusable, very slow and laggy, as can be seen from the video

The menus take ages to close, as well as windows, switching between tabs has more or less the same issue.

My laptop configuration is:

• Lenovo ThinkPad T480S
• Intel(R) Core(TM) i5-8350U CPU @ 1.70GHz
• 23.2 GiB of RAM
• Mesa Intel® UHD Graphics 620
  

I tried to tweak the quality settings, switchet from ultra to medium, but apparently nothing has changed.

Also when unity is started, the overall machine performance is pretty degraded. Any idea?

Any idea on how to improve the situation?
I have it installed on fedora and is working decently.

 

Quality settings will not affect the performances of the editor.

Looks like you're on KDE. First check that the compositor is enabled, search for it in KDE's settings.

On Unity's side try switching to Vulkan in project settings and try tweaking the Interaction Mode in Preferences.

 

Thanks enabling the compositor make things much more smoother.
