Can you be more specific? I failed to find out how this change can break the accelerated animation, and I made sure this change doesn't break both the animation and the transition layout tests on the Qt port enabling accelerated compositing. 432348 6 simon.fraser 2011-07-05 11:24:55 -0700 I'm not sure that Qt does accelerated animations the same way that Mac does. Does it ever return true from its GraphicsLayer::addAnimation() method? 432864 7 joybro201 2011-07-06 10:24:48 -0700 (In reply to comment #6) > I'm not sure that Qt does accelerated animations the same way that Mac does. Does it ever return true from its GraphicsLayer::addAnimation() method? I just ran layout-tests for animations, transitions and compositing on the Mac port in which accelerated compositing is enabled in default, and made sure no testcase fails by this patch. It seems no problem :) > if (!m_startTime) { > // If we haven't started yet, make it as if we started. > m_compAnim->animationController()->receivedStartTimeResponse(currentTime()); > } > > ASSERT(m_startTime); As I wrote in the changelog, the above code has not worked at all, so the next Assertion always fails when the m_startTime is zero like Bug 59475. In other words, this change could affect the testcases that have hit assertion failure, and doesn't make things worse at least. 432865 8 simon.fraser 2011-07-06 10:31:11 -0700 (In reply to comment #7) > (In reply to comment #6) > > I'm not sure that Qt does accelerated animations the same way that Mac does.

I think the failure would only show there.

If you tell me why you think this change causes failure on accelerated animation, I can dig into that more. 433457 10 99556 simon.fraser 2011-07-07 08:00:01 -0700 Comment on attachment 99556 Patch OK 433461 11 joybro201 2011-07-07 08:07:18 -0700 Thank you for your review, simon :) 434976 12 joybro201 2011-07-11 10:26:15 -0700 Simon, could you commit this, please?
