    <thetext>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&apos;s not a regression in WebKit, but somewhere else in the graphics stack, but it will probably soon be visible to users so we&apos;ll have to deal with it now.

Of course I don&apos;t know how to fix these issues, and I don&apos;t think we should release in this state, and we&apos;ve reached the end of the release cycle, so I&apos;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&apos;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</thetext>

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