Strange chars on firefox (9gag example)
it looks like with some update this is gone, still I let this open for a week or two, if anybody else has the issue.

hhielscher the problem is still present. It looks like it is doing that the only one kind of font. What kind of info should I post to address this issue? after upgrade to ff16 the problem still persists. The problem also appears in libreoffice Maybe a pango or a cairo issue... CC:

thierry.vignaud I have changed the default font in firefox from helvetica to freeserif, I still have those things sometimes, but it definitely got better. Other plus info, that after ff loads the full page these characters are usually disappeared, as well as after scrolling to somewhere else on the page and scrolling back does the same. The problem sporadic and as I have written it vanishes on several actions, but it is still annoying. Please let me know what information I can provide you or what can I do to debug/address the problem source at least. Cheers! New symptom: Instead of strange characters now those just vanished... I have the same problem (Cauldron, Dell Latitude D830, Nvidia Quattro NVS 135M, Nvidia driver 304.60). There seeem to be two issues in that area, reported and fixed in the X server: https://bugs.freedesktop.org/show_bug.cgi?id=47266 https://bugs.freedesktop.org/show_bug.cgi?id=55723 Both issues have patches and users report the problem being solved. From looking at the source RPM of x11-server-1.13.0-6mga.3 I can see the patch for the issue 47266, but not 55723. Can someone, please, check? Thanks, Vladimir CC:

mageia An x11-server is being pushed with that patch. Please test once it lands on your favorite mirror I really would, but for now, mageia.supp.name has no cauldron at all:( Hello Thierry, So far looks quite good! I'll let it run a little longer (and I have several of these laptops), but I keep my fingers crossed. BTW, when I tried to rebuild the X server myself, I got a LOT of warnings (with or without this particular patch). Is that expected? Thanks, Vladimir That happens. It depends on upstream developers. Status:
NEW =>
RESOLVED Well, I have some bad news... While the problem is definitely much less pronounced, eventually corrupted characters appeared on several systems. I'd suggest we still keep this patch, but we need to watch XOrg server for the additional developments Status:
RESOLVED =>
REOPENED I can confirm, that since the X server update, de characters are goo again (after one day of testing at least) Sadly the problem is present though it is much less annoying at this moment, I will upload a new screenshot too if I can catch it... Created attachment 3073 [details]

The problem is due to an incompatibility between this patch: use-new-pixman-api.diff to use the new experimental pixman glyph cache. and the nvidia drivers (any version). See for instance: https://devtalk.nvidia.com/default/topic/524242/linux/pixman-glyph-cache-patch/ https://bbs.archlinux.org/viewtopic.php?id=152837 https://bugs.archlinux.org/task/32612 According to the nvidia link, a nvidia dev managed to reproduce the bug and fixed it in a version to come. I personally encounter this bug all the day, like people in these forums (and others). CC:
