https://bugs.freedesktop.org/show_bug.cgi?id=37417 Summary: No Alpha Channel for all XPixmaps with KWin+GLES Product: Mesa Version: 7.10 Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: mgraesslin@xxxxxxx Created an attachment (id=46961) --> (https://bugs.freedesktop.org/attachment.cgi?id=46961) ARGB window without alpha channel After updating mesa on Debian Testing to package version 7.10.2-2 everything mapped from a XPixmap lost the Alpha Channel. ARGB windows are no longer translucent (screenshot attached) as well everything else mapped from an XPixmap. This only affects OpenGL ES/EGL build of KWin, building against desktop GL/GLX does not show the symptoms. Debug output of KWin with GLES: OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD RV710 OpenGL version string: OpenGL ES 2.0 Mesa 7.10.2 OpenGL shading language version string: OpenGL ES GLSL ES 1.0.16 Driver: R600G GPU class: R700 OpenGL version: 2.0 GLSL version: 1.0.16 Mesa version: 7.10.2 X server version: 1.10.1 Linux kernel version: 2.6.38 Direct rendering: yes Requires strict binding: yes GLSL shaders: yes Texture NPOT support: yes Debug output of KWin with GLX: OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: Mesa DRI R600 (RV710 954F) 20090101 TCL DRI2 OpenGL version string: 2.1 Mesa 7.10.2 OpenGL shading language version string: 1.20 Driver: R600C GPU class: R700 OpenGL version: 2.1 GLSL version: 1.20 Mesa version: 7.10.2 X server version: 1.10.1 Linux kernel version: 2.6.38 Direct rendering: yes Requires strict binding: no GLSL shaders: yes Texture NPOT support: yes This worked fine until update of the package. KWin has not changed (recent master, build from today). If you need any help to investigate, please ask. We want to push the GLES build of KWin with our upcoming release (beta 1 next week). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
