The problem is that the 16x30 font causes the cyblafb imageblit to fall=20 back to cfb_imageblit for rotation 1 and 3 while the accelerated copyarea=20 function is still used. That breaks the private sync mechanism of cyblafb and causes=20 the erroneous behaviour. I=B4ll publish a patch soon. cu, Knut ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
