Describe the Bug
Weird input buffering is occurring after several UI events of certain kinds. The attached .gif shows this in the menus.
It also happens with mouse-wheel scrolling in the code editor, but this is harder to demonstrate in a screen cap. I scroll down 3 notches, the editor moves down only 2. I scroll up three notches, the editor moves down 1, then up two. The third down has only been applied when I scroll up once. In other words, every movement is one step behind.
Occasionally, when something falls behind, it causes the entire UI to become pitch black for a moment, and nothing is visible.
Steps to Reproduce
Move the mouse back and forth over the menus. Scroll back and forth in the editor.
Expected Behavior
Mouse pointer and scroll wheel movements take effect immediately. There is no input buffering.

Additional Information
This has been happening for a while on my system, but I thought the lag issue that’s blowing up might be related somehow, so reporting it now. Notably, VS Code doesn’t suffer from this issue. My workstation has plenty of memory, storage, and compute.
Does this stop you from using Cursor
No - Cursor works, but with this issue
