Description Michael Catanzaro 2019-01-29 11:52:16 PST

In bug #192523 we are tracking a few issues with accelerated compositing mode. In particular, I consider bug #192522 a blocker for 2.24. It's not a regression in WebKit, but somewhere else in the graphics stack, but it will probably soon be visible to users so we'll have to deal with it now.

Of course I don't know how to fix these issues, and I don't think we should release in this state, and we've reached the end of the release cycle, so I'm left with unhappily suggesting that we switch the default WebKitHardwareAccelerationPolicy to WEBKIT_HARDWARE_ACCELERATION_POLICY_NEVER, at least temporarily. If graphics developers have other suggestions, I'm all ears, but bug #192522 is very severe.

Problems this will cause:

 * 3D transforms will be broken
 * Performance on tablets and phones will be tanked; these are important targets for GTK port

I wonder if this has been fixed in bug #193903. I will investigate that first.

Carlos Garcia doesn't want to do this. Closing.
