I recently reinstalled my system with PopOS 20.04. In general everything runs fine. the only new problem which came up for me was that one of my three Vive Trackers 2018 dies because of empty battery, the vrcompositor segfaults and my VR screen turn black. This is the entry I get in dmesg when it crashes:

[50542.640286] RenderThread[183521]: segfault at 10 ip 00000000005927b1 sp 00007fa951df33c0 error 4 in vrcompositor[400000+377000]

And not too sure if it's related to it, but a few seconds later, another segfault pops up in dmesg:
