[vbox-dev] [PATCH] Fix non-ARGB texture issues

[Erkin Bahceci]

Hi,

Attached is a patch that fixes the texture issues with non-ARGB
windows (when running Compiz on the guest), that happen due to all
texture images being unconditionally specified with the GL_RGBA
internal format in guest additions. The issue can be seen during fade
animations or when you reduce the opacity of a non-ARGB window ( e.g:
http://imagebin.ca/view/6Bujs1.html ). The same bug also causes
screenshots taken with the Compiz screenshot plugin to come out
partially transparent.

This patch is under the MIT License.

Regards,
Erkin
