Thanks for handling this, I have 2 questions: did you check we get improvements with the patch in benchmarks (MotionMark)? And this patch is actually obsolete and we need to use the new ones in this bug and the one that depends on it:

That is why if you have any time and can help to check how is the current situation it would be helpful ;-), :pray:

Yes, I notice small changes are required for WEbKit on main but still applies find for 2.36(stable) where this patch is being applied here.

Tested on several boards iMX6, rpi3 rpi4 (64 bits) the impact is consistent. The patch bost up the results of MotionMark tests. In particular Leaves and Images with improves the marks in x2 x5. E.g. those are the results before-after for the RPI3.

After talking to Pablo I think we can push this patch until we have a better solution we are creating for upstream, which is more polished. Thanks!

After talk with @alexgcastro @zdobersek we agreed to keep waiting for a more revamped version of the patch. There are some ideas for improving the patch but we still need to gather some more information.
