Summary: Rendering issue occurs after restarting in Safe Mode in OS X → Rendering issue occurs after restarting without HWA (or in Safe Mode) in OS X
CreateRenderTargetForWindow might clear too aggressive which means it would clear unwanted area.
So I add ClipToRegion in advance to prevent it from clearing those unwanted area.

Try looks good. The orange happened on OSX is caused by another commit.
