Description Gerd Herrmann 2025-11-27 16:36:13 UTC
Description:
When EDITING a cell, I have a "double cursor" - one (the real one) at the position which will actually be changed when I enter sth., and another one 1 or 2 positions left to this. 
When moving in the cell, the cursor and this one-left-shadow move together, with 1 or 2 positions between them. 

When I move the real cursor to the very beginning of the cell to the left, the "shadow cursor" is shown left outside the real cell. 

THis is NOT seen when in save mode (user profile reset), but back when in regular mode again.

Steps to Reproduce:
1.Start Calc in normal mode
2.Calculate something 
3.Start EDITING one of these cells where values are entered (F2)  ==> it shows (with me) this shadow cursor.

Actual Results:
When editing a cell I see a shadow curser, which is confusing

Expected Results:
See / show only the actual cursor position in a cell


Reproducible: Always


User Profile Reset: Yes

Hello Gerd Herrmann,

Thank you for reporting the bug. I was unable to reproduce the bug following your instructions. 

This issue may only be present when running on Windows 11, as I did test with the same version but on Windows 10.

I am leaving this as UNCONFIRMED so another tester may be able to test it again on Windows 11.

Remark: Can`t confirm by myself the same error on another windows machine (or Linux, for that matter).

Reported machine runs Windows 25H2, machine NOT showing "double cursor" runs 23H2. Maybe it would be a good practice to ask for the specific Windows version rather that "Any Windows".

In the machine that shows the issue, does it make a difference, if you deactivate this option: Tools - Options - LibreOffice - View - Force Skia software rendering?

Re: disable Skia software rendering: YES, that solved it. Once it was OFF, that weird error did not occure. When switched back on, the "double cursor" appears again.
