Hello, I'm using Unity 2019.4.17fi with Arch Linux and i3 environment with xcompmgr. Whenever i try to move around a Unity window (such as the tile palette for example) it freezes and randomly swings around and i get a lot of errors, is there anything i can do in the 2019 release or do i need to switch to a more recent one ? Here is my error message : (i put it in a C# code because i think it would be more readable like that) Code (Csharp): ArgumentException: Getting control 0's position in a group with only 0 controls
