[Nouveau] [Bug 30286] New: Rendering Artefacts for "EffectFrames" with KWin trunk
https://bugs.freedesktop.org/show_bug.cgi?id=30286 Summary: Rendering Artefacts for "EffectFrames" with KWin trunk Product: Mesa Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/nouveau AssignedTo: nouveau at lists.freedesktop.org ReportedBy: kde at martin-graesslin.com Created an attachment (id=38827) --> (https://bugs.freedesktop.org/attachment.cgi?id=38827) PresentWindows effect showing artefacts. I noticed that KWin's EffectFrames are rendered incorrectly with nouveau and current kwin trunk (please see attached screenshot). There has been a change between 4.5 and current trunk, so I cannot say if the same problem exsists with 4.5. as well. The EffectFrame is a GLTexture generated with TextureFromPixmap from a Qt QPixmap. In the screenshot we see that the icons are rendered correctly (also using QPixmap -> TFP -> GLTexture conversion) while the other textures are rendered incorrectly. This includes the pure black background texture, the textures generated from Plasma's FrameSvg and text textures. The relevant code is in kwin trunk scene_opengl.cpp [1] SceneOpenGL::EffectFrame::render() at line 2002. An example for creating a texture can be found in SceneOpenGL::EffectFrame::updateTextTexture() at line 2264. If you want to have any other information to the code, do not hesistate to ask, as I recently refactored that code. I am using nouveau, dri and kernel from debian experimental. glxinfo says it's Mesa 7.8.2 [1] http://websvn.kde.org/trunk/KDE/kdebase/workspace/kwin/scene_opengl.cpp?view=markup -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

[Nouveau] [Bug 30286] Rendering Artefacts for "EffectFrames" with KWin trunk
https://bugs.freedesktop.org/show_bug.cgi?id=30286 --- Comment #1 from Martin Gr??lin <kde at martin-graesslin.com> 2010-10-10 04:29:24 PDT --- I added a workaround to KWin by keeping the QPixmap around as long as a texture is bound from that pixmap. SVN commit 1184458 by graesslin: Make EffectFrames work with Nouveau driver. This worksaround a problem with the nouveau driver causing the text frames to be incorrectly rendered. We need to keep the QPixmap around as long as we have a texture created from that texture. This applies for the text and the unstyled effect frame. For the frames generated from Plasma's FrameSvgs it is not required.
