[Qt-interest] mixup of RGB/BGR mode when using "-display Transformed:Rot90"

Dear all,

I am sending this posting again on this list because I did not receive any 
reply on qt-embedded-interest.(the list does not seem to be very active)

I am using Qt Embedded 4.5.0 on an embedded device around an ARM9 
microcontroller running embedded linux.

When I am running applications with the default screen driver using a 
16-bit framebuffer everything looks ok. 
However, when I use the "Transformed" driver, in order to achieve a 
display rotation of 90 degrees, all color seem to be mixed up. Red colors 
appear in blue and vice versa. Seems like something get's mixed up with 
RGB/BGR settings.
If I pass the argument "-display Transformed:Rot0", then the colors are Ok 
as well. 

Seems like a bug in the "Transformed" driver.
Any comments on this?

Mit freundlichen Grüßen / Best regards

Markus Franke
