expected result

actual result
It seems that composite assumes a source drawable is always at (0, 0).
This is true for pixmap and redirected window, but not for unredirected window.
Created attachment 43840 [details] [review] possible fix Does this patch help? Do solid and copy need something similar? (In reply to comment #9) > It seems that composite assumes a source drawable is always at (0, 0). > This is true for pixmap and redirected window, but not for unredirected window. Sorry, please ignore this. I am confused. The patch doesn't fix the problem. It also breaks redirected window. This is not something the driver should need to be concerned with. If the driver acceleration hooks aren't called properly, that needs to be fixed in EXA or maybe even higher up. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
