Under Wayland it is very difficult to use active corner, or activate an hided panel like Latte Dock, because the cursor stops few pixel from the region of activation.

Detailed description of cursor behaviour:
Pushing the cursor towards the active corner/region it runs smoothly for the entire screen than stops few pixel from the screen border, at this point it is possible to push further the cursor but there is not enough space to gain the necessary "momentum" to activate the function set at this corner/region.
