I’m trying to run through some training material on Unity on Ubuntu, and am running into problems trying to edit materials. When I create a material and view it in the Inspector, then click on the Albedo colour selector, the editor becomes highly unstable; an unusable Color window appears either mostly off screen or entirely off screen, the editor slows to a crawl and displays the warning message “PropertiesGUI() is being called recursively. If you want to render the default gui for shader properties then call PropertiesDefaultGUI() instead” After a while the Color window vanishes. Repeating this a couple of times leads to a crash.
This happens every time I try to change the colour, on 2021.1.2f1 and 2020.3.3f1 (LTS), both installed via UnityHub.AppImage, which makes Unity absolutely unusable.
Any suggestions?
