Previously, if there were several buffer swaps scheduled for the same vertical blank, all but the first blit emitted stood a chance of exhibiting tearing. In order to avoid this, split the blits along slices of each output top to bottom. Signed-off-by: Dave Airlie <[EMAIL PROTECTED]> (and yup, that's how the Author: is recorded in git) Unfrortunately that patch doesn't trivially revert, so I can't send you a patch to test. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
