    Had the same bug with Unity 2019.4.18f1 and 2020.2.5.f1 to 2020.2.7.f1 on Linux Mint 20.1. Graphics Card is Radeon RX 570. Also what's weird is that the crashes occur far more often with a new/custom scene then with the standard sample scene in all versions i tested. If i modify the sample scene and enter playmode several times, it crashes mosty after the 4th time entering/leaving Playmode, sometimes not even then. With a new scene, Unity most of the time crashes after the first time entering or leaving Playmode, even if there is just 1 cube in the scene.
