-Subject: [PATCH] Fix wrong cursor hotspot under Wayland on VMs
-
-This backports the key parts of 998bbf4 to the 5.22 branch,
-where the code is substantially different. It solves a problem
-where the click point is slightly offset from the position
-indicated by the displayed cursor when running on Wayland in
-many VM configurations (e.g. qemu with qxl or virtio GPU).
