RenderDoc crashes on Linux with Mesa on intel printing 'intel_do_flush_locked failed'

[Vtec234]

Hey,

QRenderDoc 0.33 crashes on my Linux system with Mesa after opening any log and clicking on Mesh Output or Texture Viewer. Without a log open these panels work fine and I am able to capture an executable. I tested this with captures from two different executables. There is one line in stderr:

intel_do_flush_locked failed: Invalid argument

and here is the log:

As far as I know this is a mesa bug, at least I chased it as far as I could in renderdoc and got nowhere. See #515 and the mesa-side bug https://bugs.freedesktop.org/show_bug.cgi?id=99831

[Vtec234]

Ah, I see. I'll close this and sorry for the double report. Hopefully Mesa can fix this, although the priority doesn't seem high.
