[Nix-dev] ati_unfree drivers, HD 5650 mobility radeon - slow font rendering ?

[Marc Weber]

After some time (maybe 10min up to 2 hours) font rendering gets that
slow that a vim instance (gvim/vim/xterm/emacs) takes about 3 seconds
to render the fonts. I've not found a solution yet.

Does anybody have an idea what could try?

Same setup on a different machine (intel on board) works flawlessly.

I didn't try to find out the commit causing the problem yet.
