Weird bug in Excel 2024 LTSC when switching sheet direction (RTL issue)

Several users have reported experiencing this issue, and there is an open feedback ticket (ID: 81911365-f23c-f111-9a91-7c1e52d4091c). However, Microsoft has not yet officially confirmed or responded to this report.

Workarounds (Until Microsoft Patches It)

Since reinstalling doesn’t help, try these temporary solutions:

 1. Avoid changing sheet direction
Keep workbooks in LTR mode if RTL is not strictly required for your data layout.

 2. Use keyboard shortcuts for selection

• Ctrl + Space → select entire column
• Shift + Space → select entire row
• Ctrl + Shift + Arrow keys → extend selection
  The selection border may still be invisible, but the selection is active.

 3. Toggle zoom level
Press Ctrl + scroll wheel to zoom in/out by one step — sometimes this forces a redraw of the selection border.

 4. Switch to Excel 2021 for RTL-heavy work (if licensing allows), as the issue does not exist there.

 5. Use “New Window” feature

• Go to View > New Window
• Work in the duplicate window — some users report selection highlighting works better there (though it’s not a perfect fix).
