I am experiencing a persistent issue with my system, even after updating to the latest Windows version. My system runs on Windows 11, version 23H2, build 22631.2715. I use an external monitor connected through DisplayPort v1.2, supporting a resolution of 5120x2160. The problem occurs when my system wakes up from sleep mode. Often, the taskbar is completely empty, with no icons visible.
As a temporary solution, I right-click on the desktop, go to Display settings, then to Advanced Display. Here, I change the Refresh Rate and immediately revert it back. This action brings back all the icons on the taskbar. I've also noticed that manually putting the system into sleep mode results in this issue happening less frequently.
(I have reported this via the Microsoft Feedback Hub).
