Bug description

By far the most egregious issue with Linux Mint in the past two years has been this bug: https://github.com/linuxmint/muffin/issues/659

It has remained intact in every major release since Linux Mint 21. In summary, tiling windows to the left or right side of the screen in some pattern causes the mouse's interaction to become offset by an arbitrary distance. This borks everything from drag-and-drop to the spawn of the right-click menu, to your ability to simply click on what you want, and only undocking the window you're in temporarily resolves the issue. I hate it.

HOWEVER, in attempting to troubleshoot this issue in Linux Mint 22, I have encountered an entirely new bug which borks drag-and-drop for what appears to be the remainder of your session. It's VERY finnicky to reproduce and while my reproduction steps involve a live environment and the experimental Wayland session, this bug is NOT exclusive to the experimental Wayland session.

I have used the following steps to reproduce this issue 3 times.

Steps to reproduce

• Boot into Linux Mint 22 (64bit) from a live stick.
• Right-click on desktop to Create New Folder, name it "Test".
• Double-click into Test, right-click to Create New Document in Test, name it "test.txt".
• Logout
• Log in using Experimental Wayland Session
• Double-click into Test
• Dock Test to left side of screen.
• Close Test.
• Double-click into Test.
• Dock Test to left side of screen.
• Click File > New Window.
• Dock New Window to right side of screen.
• In New Window, click Documents shortcut to open Documents. You should now have Test open and docked to left and Documents open and docked to the right.
• Attempt to drag-and-drop test.txt from Test to Documents.

It does not work.

Expected behavior

test.txt is moved from Test to Documents.

Start by reproducing the failure with the listed Linux Mint 22 live-environment steps, including the experimental Wayland session and docked Test and Documents windows. Investigate the drag-and-drop path around that window arrangement; done means dragging test.txt from Test to Documents moves the file reliably, while preserving the documented expected behavior.
