Thanks for the information, really a relief to know that this is being worked on. Does this aim to achieve as good performance as with "legacy DC" for every window operation as well? Would it work to do something like "patch -Np1 -i -R fastcursorpath.patch" and then apply the new set of patches? In that case my question would be how to find the right patch to revert. The PR for the kernel included much more (yeah, sorry for such beginner questions): https://github.com/torvalds/linux/commit/74136a3d47f51ae72ee8b9ebc1ec2a29bcf30676
