I think I would prefer to keep it, since there will be no drawing without it when accelerated compositing is not available. Maybe the temporary window could be created with a different style? From the current style, it seems it won't get activated. 1559817 4 fujii 2019-08-08 23:34:36 -0700 I found a serious issue of AcceleratedCompositingContext::acceleratedCompositingAvailable on Windows 10 version 1809 or newer (Bug 200563). I can't find a solution for both issues (Bug 200563 and Bug 200493). Let's revert it until someone wants to solve these issues and the original issue (Bug 140667). 1562886 5 375676 fujii 2019-08-19 18:58:29 -0700 Comment on attachment 375676 Patch Clearing flags on attachment: 375676 Committed r248885: <https://trac.webkit.org/changeset/248885> 1562887 6 fujii 2019-08-19 18:58:33 -0700 All reviewed patches have been landed.
