Bug 198418 – REGRESSION(r244182): [CoordinatedGraphics] Related view doesn't receive graphic updates

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Carlos Garcia Campos]

This is because we need a DisplayRefreshMonitor per drawing area, but the one from the first ThreradedCompositor is always reused because they use the same display ID.

If you can find a better way to make that page ID into a 32-bit, then go ahead.
