[Qgis-user] Qgis-user] QGIS 3.8 on Debian 10 slow and crashing

[Raúl Nanclares]

Hi  Micha, i've been doing some testing this week, i couldn't reproduce the
issue adding a new gpkg to an old project. What i have noticed is that
starting the user session using Xorg completely removes the crashes, I'm
still seeing some random QGIS lock-ups but i couldn't find any hint of what
is causing it. I will continue using xorg and see if i can find
what's going on.

Cheers!

Raúl
