Bug#899099: freecad crashes at start with reference to XInitThreads

[Kurt Kremitzki]

Hello Luc,

This sounds similar to an issue reported in the FreeCAD forums [1] for
which the following workaround is suggested:

"A workaround is to either disable DRI3 for all applications by adding
the following line to /etc/environment

LIBGL_DRI3_DISABLE=true

Or to disable DRI3 just for Freecad by launching freecad from the
terminal with the following command.

LIBGL_DRI3_DISABLE=true freecad"
