Font corruption

Hello everyone,

since a long time, I've been experiencing slight font corruption in Gecko powered applications (Firefox/Thunderbird), that were going away when highlighting the culprit characters. Lately I've been getting it, except that it's worse, doesn't go away (I suspect the new GTK or kernel) and happened in Geany too.

Xorg logs don't have any errors and dmesg only show

radeon 0000:01:00.0: Packet0 not allowed!

repeatidly. The issue doesn't seems to be a hardware problem since it only happens with specific applications. I tried switching from Glamor to EXA, without success and memtest86 says that my RAM is okay.

Using radeonSI with an AMD radeon R9 280X (7970).

A picture of the problem.

Thanks for your attention.

Re: Font corruption

I would try disabling "damage" in xorg, e.g. /etc/X11/xorg.conf.d/50-damage.conf, containing:

Section "Extensions"
    Option  "DAMAGE"  "False"
EndSection

Re: Font corruption

Thanks a lot. It seems to solve the problem, for the moment. By the way, do you have any idea of the causes?

Re: Font corruption

Alright, it seems rarer now (maybe placebo), but it's still not gone.
