|

When using the fb backend at 24bpp it allows a visual with 32 bit depth.
|
||||
When using CopyArea from a 32bpp pixmap to a window with a 32 bit depth it would
|
||||
read the ARGB as RGB.
|
||||
|
||||
Fix is to correctly ignore the alpha channel in the pixmap when copying.

When using the fb backend at 24bpp it allows a visual with 32 bit depth.
|
||||
This would cause RENDER to try and create an invalid pixman buffer and hit the

following assertion when trying to render to it:
