--- Comment #11 from Lubosz Sarnecki <lubosz at gmail.com> ---
This bug affects all application using Qt5 QtQuick 2 applications build with
MSVC run on i965.

http://en.wikipedia.org/wiki/Qt_Quick

The MSVC Qt5 SDK uses the ANGLE graphics layer, in contrary to the MinGW one,
which uses Desktop OpenGL.

https://code.google.com/p/angleproject/

Since native Qt5 Linux applications do not use ANGLE, only applications using
wine are affected.

I have uploaded precompiled versions of the QtQuick clock example, one using
MinGW, the other one MSVC.

The bug only occurs for the MSVC/ANGLE version.

I also uploaded apitraces of the native Linux version and wine with MSVC and
MinGW.

All traces can be played back on nouveau and swrast (e.g.
LIBGL_ALWAYS_SOFTWARE=1). 
The MSVC/ANGLE traces cannot be played back on i965. All software versions on
both systems are identical.

Traces using MSVC/ANGLE recorded on nouveau also cannot be played back on i965.

Analyzing the MSVC/ANGLE trace with qapitrace on i965 shows that the texture is
uploaded correctly, but apparently not displayed correctly.
