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@lists.freedesktop.org

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).
