cursor location sometimes locked and not consistent with display

[ggggggggg]

Describe the bug

I used the mouse to click on a place I wanted to type, then typed and the cursor jumped to a different location and entered my character. I then deleted that, click the mouse to move where I want to type, and typed again. The cursor jumped back. This state persisted until I did "restart kernel".

I haven't been able to consistently reproduce it, but it has happened to me multiple times across a few days.

Thanks. We've heard this from several users now. We'll try to repro and fix.

An example of this issue raised by another user on Discord:

"Got an error at the end of a notebook, when I start typing, it somehow jumps back a character or two to inside the previous )"' character"

@ggggggggg is this still happening. we've had many upgrades to the underlying library so it may have been fixed

I have not seen this in quite a while. It may well be fixed. On Thu, Feb 13, 2025 at 3:17 PM Myles Scolnick @.***> wrote:

Going to close, but we can always re-open if it surfaces.
