Is this still an issue?
What graphics hardware do you have?
Please attach the outputs of dmesg and
LC_ALL=C lspci -nn | grep 'VGA compatible controller'

So it looks like it wants to load the intel module but can't find it.
Do you have intentionally removed the package xserver-xorg-video-intel?

As fallback it uses the modesetting driver.
There seems to be an issue in either modesetting, glamor or the 3d mesa
