The display does not look right when running on OMAP3 EVM with "-display powervr" and VRBF enabled

When running on OMAP3 EVM with "-display powervr" and VRBF is enabled for rotation, the display screen does not look right.

For your information, found a soution to this problem:

in pvrqwsdrawable.c

the line
stride = var.xres * bytesPerPixel;

should be replaced with
stride = fix.line_length;
