I’m trying to fix an issue with the mouse cursor rapidly switching between the arrow pointer and link cursor (hand) in Firefox and arrow pointer to i-beam in Sublime text. This occurs when the window is in focus and the mouse cursor is moved across the screen — please see the screen recordings:
Any known fixes or steps to further diagnose? There are mentions of this on other discussion forums but none I could find with this exact behavior. This bug report for a different application describes my problem most closely: https://github.com/keepassxreboot/keepassxc/issues/3595.
What I’ve observed:
- Seems to occur when multiple windows of a given application are spread across different “Spaces” in macOS. * As shown in the second screen recording, the cursor gets buggy at the point when the Firefox window in screen 3 is partially “overlapping” another Firefox window in screen 9.
- I’ve struggled to replicate this behavior consistently and the buggy behavior seems to emerge on its own after a certain amount of time. It is possible that resizing windows will also initiate the behavior.
- As mentioned, most commonly occurs with the Firefox browser and Sublime text editor presumably because those are the most used apps but I’ve observed this with other browsers, the Mac calendar apps and others.
- Same behavior with external pointer (logitech track ball) or built-in Mac touch pad. Same with external monitor plugged in or with built-in display.
I’ve attempted without success:
- to boot in safe mode — behavior persisted.
