[Win] Prevent flashing/strobing repaints on certain hardware
https://bugs.webkit.org/show_bug.cgi?id=152394
<rdar://problem/23875302>
Reviewed by Simon Fraser.
This patch reverts a change I made in r192166, where I always set the
m_viewNeedsUpdate flag to true when a 'flushContext' call was made. Instead,
we should go back to letting the view decide when it needs to paint.
* platform/graphics/ca/win/WKCACFViewLayerTreeHost.cpp:
(WebCore::WKCACFViewLayerTreeHost::flushContext): Don't just claim that
the view needs to be updated any time we are asked to flush.
