Cursor jumping to top left of stacked windows when using shortcut to switch

[ProspectPyxis]

(1) Issue/Bug Description:

When switching between stacked windows using keyboard shortcuts (Super+H and Super+L in particular, though any other custom shortcuts do the same thing), the cursor seems to jump to very near the top left of the window affected. As far as I know, this has not happened until recently on my end.

Here's an image of how it looks like:

(2) Steps to reproduce (if you know):

1. Stack at least two windows together.
2. Use keyboard shortcuts to cycle between them.

Unfortunately, I have no idea how the bug activates - it seems to have started out of nowhere, and has been a consistent issue since it started.

(3) Expected behavior:

The cursor should stay where it originally was.

(4) Distribution (run cat /etc/os-release):

Pop!_OS 20.10

(5) Gnome Shell version:

3.38.2

(6) Pop Shell version (run apt policy pop-shell or provide the latest commit if building locally):

This is a feature under an Xorg session. On Wayland you won't have this.

Hm...I'm aware that this might fall out of the scope of pop shell specifically, but is there any way to disable this within xorg? Reading through the issues page, it seems this with wayland still has some issues to resolve, so I'd like to avoid that if possible.

[mphojele]

I use a wayland session. Anyways, I can't seem to find an obvious way disable this feature. Code related to it is in

shell/src/config.ts

Line 67 in 1c110ff

/** Move pointer when you switch applications */

and

shell/src/window.ts

Line 555 in 1c110ff

/// Activates a window, and moves the mouse point.

A hack would be to comment out line 560 in src/window.ts, but when you run make local-install it might complain because the function would be defined but never called, which means comment out the function definition as well.

Wow, if this was implemented two months ago according to the blame, I really wonder how I haven't noticed it as a problem until now. Either way, I find it really weird that there's no way to disable this easily right now, despite the configuration option for it being right there (but unused as far as I can tell)...how hard would it be to add it as an easy configurable option, in that case?

[mmstick]

This has been a feature since before Pop Shell supported tiling, because it improves mouse utility on ultrawide displays. But I can disable this for switching between stacks, since it's not necessary to do so for stacked windows.

[ProspectPyxis]

Ahh, that makes more sense. That does sound like a good solution.
