Describe the bug

Apologies - originally posted in wrong section. Here it is in the right section for "Bug reporting".

Version 4.4.198 results in black bands overlaying the Excel 365 tabs bar at the bottom of the screen and bad rendering of cell colours. Only Excel 365 and Excel 2021 are affected - Word is not affected, have not tried PowerPoint. It happens only in RDP mode when the RDP host is either Windows 2019 Server RDP server (all users affected, particularly but not exclusively when minimizing remote to go local and switching back to remote), or, occasionally, Windows 11 Pro. Graphics Acceleration turned OFF in Excel.

Reverting back to 4.4.196 thankfully removes all the problems.

Have used 4.3.1 all the way to 4.4.196 on that Windows 2019 RDP server without a problem ever - only the latest version, 4.4.198 has this problem.

Area of issue

Installation/Other

To reproduce

Set it up on Windows 2019 Remote Desktop Server or Windows 11 Pro, access in RDP mode, use Excel 2021 or Excel 365.

What tends to always reproduce the problem is minimizing the remote session to do something on the local PC, then switching back to the remote.
