Since the most recent rolling release of Manjaro Linux, the shaders fail to compile, leaving only an unusable window with no content. The log is pretty huge, I provided it here: ts.log - Google Drive
As rolling releases update a large number of packages, I unfortunately have no idea which one caused the problem. The systems I tested on both use an AMD Ryzen CPU with an iGPU (5850U, 7950X3D).
I tried both the AUR package and the .tar.gz
directly from the TeamSpeak website.
