            Bug ID: 157312
           Summary: Current cell highlight doesn't update with skia
                    hardware rendering on Macbook Air M2
           Product: LibreOffice
           Version: 7.6.0.3 release
          Hardware: All
                OS: macOS (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: graphics stack
          Assignee: libreoffice-bugs@lists.freedesktop.org
          Reporter: s...@sebwills.com

Description:
With a default installation of LibreOffice Calc, the blue border around the
focus cell doesn't reliably update when the current cell is changed with the
arrow keys. The shading on the row/column headers does move, showing that it is
just the rendering of the border around the cell that is not correctly
refreshed.

Usually it updates with a lag of a second or two, but sometimes it waits until
the next keyboard/mouse interaction, which can result in a situation where the
selected cell appears to lag one step behind where it should be.

You can see the cell highlight is not staying in sync with the highlight in the
column/row headers.

This issue disappears when I select 'force skia software rendering' in
LibreOffice preferences.



Steps to Reproduce:
1. open Calc and put some values in a few cells
2. Use arrow keys to move the current cell around
3. Observe glitchy update of the cell border

Actual Results:
Cell border showing which cell has the focus does not refresh to correctly show
which cell has the focus. See linked video.

Expected Results:
Border moves immediately when arrow keys used and stays in sync with the
indicators on the column/row headers.


Reproducible: Always
