In WebKit2, the acceleratedDrawingEnabled pref defaults to true, but we first read debug prefs (one of which is WebKitAcceleratedDrawingEnabled) from NSUserDefaults. So, if you have a process where WebKit1 and WebKit2 coexist, and WebKit1 is set up first, you'll end up with accelerated drawing off by default in subsequently created WebKit2 views despite the WebKit2 default intending to have that preference on. 1177295 1 thorton 2016-03-23 00:09:24 -0700 <rdar://problem/25304548> 1177413 2 274767 thorton 2016-03-23 12:07:45 -0700 Created attachment 274767 Patch 1177414 3 274767 simon.fraser 2016-03-23 12:09:38 -0700 Comment on attachment 274767 Patch Do we use these defaults in WTR? 1177415 4 thorton 2016-03-23 12:15:43 -0700 (In reply to comment #3) > Comment on attachment 274767 [details] > Patch > > Do we use these defaults in WTR?
