hey so with latest steamvr 0.13.8 and blender 2.90.alpha from june 28, the VR view works on (my) GNU-linux machine !

After reading this I tested again with the latest builds but I still only get crashes on Linux and Windows.

I just cloned and made a debug build of blender and got some backtraces using gdb.
When I tried a few times I found that I actually got two different kinds of backtraces.
Each seems to be about as likely to occur as the other one:

@Julian Eisel (Severin) Please let me know if you think I can help with this in any other way (e.g. if you can't reproduce this issue).
(I tried to setup a configuration in VSCodium but I can't seem to step through the code. I can only break at breakpoints I inserted prior to launching blender somehow.)
