Hi, I've just found something which looks like a bug in the Radeon/RadeonHD EXA code. When scaling a picture in x-axis and billinear filtering is requested, the y-axis is blurred too. However the version I tested against was the one shipped with Ubuntu-9.04, and I don't have a RadeonHD powered machine myself to investigate further with latest code. Could somebody with the latest drivers please run the testcase attached (gcc -lX11 -lXrender testcase.c -o test). The expected result is a single-pixel wide line which fades out at the ends, the pathological one is a line smeared also in the y-directions. If it fails, it would be great if you could send me a screenshot :) Thank you in advance, Clemens
