Sorry for the late answer,
For the record, the "official" driver I downloaded when I encountered
the issue was the 530.30.02 version (the installer was
NVIDIA-Linux-x86_64-530.30.02.run).
I retried the 525.105.17-1 version from unstable, but the issue was
still present.
I tried the 530.41.03-1 version from experimental (while tracking
unstable for all other packages now, instead of testing before) ; I can
confirm that this version makes the issue disappears.
Again, sorry for delay in experimenting, I had not much time to try it
before.
Cheers,
JB
