[Bug 60555] New: [r300g] RADEON_NO_TCL=1 hardlock

https://bugs.freedesktop.org/show_bug.cgi?id=60555 Priority: lowest Bug ID: 60555 Assignee: dri-devel(a)lists.freedesktop.org Summary: [r300g] RADEON_NO_TCL=1 hardlock Severity: trivial Classification: Unclassified OS: All Reporter: pavel.ondracka(a)email.cz Hardware: Other Status: NEW Version: git Component: Drivers/DRI/r300 Product: Mesa This is not really a bug as normal user will never encounter this, just some nuisance I discovered when I tried to investigate bug 60552 a little bit. When RADEON_NO_TCL=1 is used (which is useful in diagnosing compiler bugs), the whole machine sometimes hardlocks. App from bug 60552 is a good way to reproduce this. This debug option should be either fixed, or if it no longer considered useful, then it should be removed. BTW this was working not a year ago, so I can probably run a bisect if needed. -- You are receiving this mail because: You are the assignee for the bug.

[Bug 60552] New: [r300g] Carvisualizer webgl demo: black flickering spots over the car

This is probably a bug in the shader compiler, as RADEON_DEBUG=noopt works around this. Specifically its the register_rename pass that causes this, when it is disabled in r3xx_fragprog.c, everything is fine. Also when I disable only the dataflow optimize pass, there is still some flickering but much less.

[Bug 59899] New: Diagonal rendering artifacts on xbmc

https://bugs.freedesktop.org/show_bug.cgi?id=59899 Priority: medium Bug ID: 59899 Assignee: dri-devel(a)lists.freedesktop.org Summary: Diagonal rendering artifacts on xbmc Severity: normal Classification: Unclassified OS: Linux (All) Reporter: aeriksson(a)fastmail.fm Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI Hi, Just moved to xbmc (which uses gl), from freevo and more often than not, I get extreme diagonal rendering artifacts on the gui. Pretty much each gui object (a box, a single character, etc) has a diagonal split and either of the halves renders o, and the other is mostly black. The diagonal flickers between the corners at a rapid pase (~ 4 changes / second). I files report on it at xbmc (http://trac.xbmc.org/ticket/14017) which also has screenshots and a short movie grab attached. Freevo worked ok, so I guess this is somehow related to new code paths executed by xbmc (both 11.0 and 12-git suffers). I have no idea if it's kernel driver related or somewhere higher in the stack. Ideas to narrow this down appreciated. xbmc is the only app which behaves like this. -ath -- You are receiving this mail because: You are the assignee for the bug.

[Bug 58131] New: r300g: Corruption in Half Life 2 unless gl_ClipVertex is written

This corruption can be seen in the static main menu(start it with -console) and in-game. The corruption goes away if I modify Wine to always write gl_ClipVertex even if clipping is disabled. This is interesting particularly because r300g does not support clipping with vertex shaders. It says so on the command line, and in-game rendering and the Wine tests confirm this. -- You are receiving this mail because: You are the assignee for the bug.

All of the labels in Google MapsGL are black rectangles. This is actually slightly worse on Mesa 9.0, with which the location names (at lower zoom levels) park, national park and state forest labels now show text on a black background instead of normal text as before. On both versions of Mesa the street names are not shown, there are only black rectangles where the street names should be. Attached screenshot is from Firefox 16.0.2 running on Mesa 9.0 on Ubuntu 12.10. The 3.5.0-2-generic #2-Ubuntu kernel is a bit out of date - I can update to the 3.5.0-17.28 kernel (which rebases to upstream 3.5.5 plus a few small changes) if that is important. Please note that this is NOT the same as bug 49088. The fix for that was specifically included in 8.0.4-0ubuntu0.1 and mentioned in the changelog. -- You are receiving this mail because: You are the assignee for the bug.

[Bug 50149] New: Faulty shaders on RS600

https://bugs.freedesktop.org/show_bug.cgi?id=50149 Bug #: 50149 Summary: Faulty shaders on RS600 Classification: Unclassified Product: Mesa Version: 8.0 Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel(a)lists.freedesktop.org ReportedBy: schmakerisko(a)gmail.com Good day, im owner of Dell Latitude XT laptop and have issues with any version of Mesa drivers. To specify problem correctly - i do have problems with shaders and textures on this laptop. On Lightsmark i do have some artifacts on screen, no (or better to say) faulty reflection. With oibaf PPA repository (git-based repository) i do have pretty much all textures black. So no luck at all. On Penumbra Black Plague GPU even causes laptop lockup - game will stop and after a moment the colors will disappear to strange white-ish recoloring and computer no longer works (hard reset required). Im upgrading to PPA drivers ATM, so if i can submit some logs or try some variables, tell me and im up to try it. Thank you for good job at the drivers. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
