xpra-start gnome-terminal libreoffice unknown OpenGL stacktrace

[stdedos]

I have no idea when or what that was. I am guessing it happened when I saved and closed LibreOffice.

Nothing really happened (everything was operating normally, LibreOffice closed / re-opened on :0 as expected), except this very big blob of red text:

Likely to be caused by:

Warning: vendor 'Intel' is greylisted,
 you may want to turn off OpenGL if you encounter bugs

The problem with the opengl error handler is that it fires on glEnd and not on the call that had the actual error (1286 = Invalid framebuffer operation)

This won't fix the problem, but may actually fix the symptoms: we should not be using video for painting libreoffice, r25521 switches to text.

[stdedos]

It has been working so far for me (I am not closing it, since you seem to want to fix it)

[Antoine Martin]

Closing as 'needinfo' since I would need to reproduce it to have a chance of fixing it.
It's probably not too much of a problem, as we should retry the paint.
