"sticky corner" on wayland with multiple screen
If running on wayland and the screen layout is like this
+-----------+
| |
| |
+-------------------+ |
| p| |
| | |
| B | |
+-------------------X |
| |
| A |
+-----------+
X seems to be a "sticky" corner, or there seems to be some "Barrier" (as I found out this is likely called) when coming from A and going to B. This is quite annoying.
This is only on wayland, when running on xorg, the corner isn't sticky at all and the pointer smoothly glides over it.
For a few days I've hunting through packages and still don't know who is responsible, so it may not be gnome-shell. I found tough, it's responsible for the barrier at "p", and I can kill that in looking glass if I want to or modifying the source, or could make an extension to override the panel barrier, that one doesn't bother as much and is less strong too.
But I still have no clue what makes the barrier at X. It doesn't seem to be the "tray" either (at least as far I can tell / have found) Also the corner is there if there are three screens, the left most is the main screen and the right most is turned like this.
Any hints how to hunt this barrier down would be greatly appreciated.
Running debian buster, with nouveau driver. (Thats also why I can't test if it's on weston and maybe a wayland issue altogether, some other weston/nouveau bug again).
gnome shell is 3.30.2.
I tried compiling and installing git HEAD, which ended with reinstalling my whole system to get it working again :)
PS: Also disabled all my extensions, restarted, the barrier is still there.
