That's SLIM then.

Yes, I can confirm this too, as this only happens with AT and NVidia
cards for me. The one in the system I tested is supported well enough to
be slow in GNOME but can play back videos without lagging.
This is due to the firmware in linux-libre not offering all the features
the blob variant would provide.

I was not able to reproduce it with anything other than GNOME.
