Summary: Canvas Accelerated Drawing shows canvas as white while
changing tabs for app using putImageData with Ca
Product: WebKit
Version: 528+ (Nightly build)
Platform: Macintosh
OS/Version: Mac OS X 10.7
Status: UNCONFIRMED
Severity: Critical
Priority: P2
Component: Canvas
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: gauravverma999 at gmail.com
canvas refresh issues with my HTML5 based virtualization application client which do frequent putImageData for the bitmaps received from server.
When I open the pages in different tabs and navigate between them, Refresh issues are seen. Canvas shows a white page and no drawing.
THIS ISSUE IS RESOLVED IF I DISABLE FOLLOWING flags in DEBUG Menu
Debug->Drawing/Compositing Flags->
Select "Disable Canvas Accelerated Drawing" and "Disable Full Page Accelerated Drawing in in New Windows"
.
Please see attached screenshots. Will try to create sample web page and update the bug.
