Priority: medium Bug ID: 81930 Assignee: dri-devel@lists.freedesktop.org Summary: [Hawaii] misrendered glyphs Severity: normal Classification: Unclassified OS: Linux (All) Reporter: kai@dev.carbon-project.org Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa
Created attachment 103698 --> https://bugs.freedesktop.org/attachment.cgi?id=103698&action=edit Latest misrendered glyph (in Firefox/Iceweasel)
When using the accelerated Hawaii setup, I'm seeing misrendered glyphs from time to time (see the attached files). They most often appear with Firefox (called Iceweasel in Debian), but I've also seen them within a less window (in Konsole).
My stack is (base: Debian testing): GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1) Linux: Git:~agdf5/linux:drm-next-3.17-rebased-on-fixes:6e07731f71 (calls itself 3.16-rc6) libdrm: Git:master/libdrm-2.4.56 LLVM: 3.5 RC1 libclc: Git:master/0ec7437d9c Mesa: Git:master/85109bc507 DDX: 1:7.4.0-2 + Patch from http://lists.x.org/archives/xorg-driver-ati/2014-July/026517.html X: 2:1.16.0-1 (1.16.0)

--- Comment #3 from Kai kai@dev.carbon-project.org --- Created attachment 103701 --> https://bugs.freedesktop.org/attachment.cgi?id=103701&action=edit Sometimes windows are misrendered as well
Very rarely I see misrendered windows as well, is this related or a different bug?

--- Comment #4 from Zoltán Böszörményi zboszor@pr.hu --- I see some misrendered glyphs on my Radeon R9 270X, too, in Firefox. So it's not Hawaii specific.

--- Comment #5 from Michel Dänzer michel@daenzer.net --- I think this is most likely a bug in the glamor glyph cache code.
(In reply to comment #3)

Probably different. There is at least one existing bug report about glamor rendering issues in KDE.
