For the record: this bug has also been reported in Debian, both Julio and the other submitter have an NV34 card on PowerPC. What about Qt apps? Do they also provoke corruptions? Can you (temporarily) downgrade cairo to <1.12 and see if it "helps"? As mentioned above, and as the screenshot depicts, this issue affects xterm too. xterm does not depend on cairo. Downgrading cairo would not (and does not) help (but I tried it anyway). Created attachment 73961 [details] [review] swap shaders on nv30 Oh, sorry, somehow I skimmed through xterm remark. Maybe something as simple as attached patch will help? Marcin: This patch does indeed seem to fix the problem. I applied it to version 1.0.1, rebuilt the package, reenabled acceleration and, voila, the fonts appear just fine. Thanks a lot! |

Created attachment 73899 [details] Screenshot depicting the issue Copy/pasting (more or less) the bug I filed with Debian about this problem * What led up to the situation? I installed Debian testing powerpc64 on a PowerMac G5 with a NVIDIA Corporation NV34 [GeForce FX 5200 Ultra] (rev a1) graphics card (as reported by lspci). The nouveau driver is version 1.0.6. Running the X server results in no fonts being displayed at all, with the exception of the default fixed font in xterm. Something as simple as "xterm -fa Monospace" also shows the problem (a blank window with a cursor but no visible text), which denotes that the issue is quite "down the dependency chain". * What exactly did you do (or not do) that was effective (or ineffective)? I uninstalled the xserver-xorg-video-nouveau package, to force the X server to fallback to fbdev, and the issue went away. The fonts are now properly displayed. Disabling acceleration with nouveau.noaccel=1 also makes the fonts work. I'm attaching a screenshot, the dmesg and the output of the X server with and without nouveau. I suspect an endianness issue is at fault.
