Summary [chromium] Fix incorrect visibility/scissor rect for threaded compositing
Adrienne Walker
Reported 2011-10-26 13:23:19 PDT
When threaded compositing is enabled, it looks like the visibility rect is wrong on the compositor thread. When the scroll on the compositor thread is non-zero, it looks like the root layer is being clipped, leading to "compositor cleared blue" or previous frames smearing in situations where clearing doesn't occur.

FYI, I don't know if it helps, but perhaps my "HACKYScrollFix" can eventually lead to a correct clean solution? That fix is not intended to be landed, but I needed it to get my scissoring to work properly just for now. The HACKYScrollFix can be found in the following attachment: https://bug-67341-attachments.webkit.org/attachment.cgi?id=112958 which is from this bug: https://bugs.webkit.org/show_bug.cgi?id=67341
