Comment 1 Christoph Feck 2019-07-03 09:39:59 UTC

Do other OpenGL applications work in remote X sessions?

Comment 2 Christoph Feck 2019-07-25 13:21:58 UTC

Crash is in libGLX_indirect, which is the remote OpenGL driver.

If you can reproduce the crash, please install debug symbols for Mesa, and report it directly to Mesa developers via https://www.mesa3d.org/bugs.html
