I think the issue went away for me after I unpinned everything from my taskbar, and then re-pinned the programs I use daily. Now, I admit, it could be coincidence. To be honest, I don't know for sure what causes this bug, or why it went away. But since the day that I unpinned and re-pinned my taskbar icons, I've not seen this issue [knocks on wood] 🙂. So I'll offer this as something you can try 🤞.
Prior to that day, I was having the same issues as everyone in this thread... somewhat randomly, maybe 3 out of 5 times, after a resume from sleep, I'd have missing icons on the taskbar, like this:
When the taskbar looks like the above, File Explorer (that's explorer.exe) would have other problems. I only got this once, but one day the address bar... the one that shows you which folder you're in... was all black, like this:
Reboot fixed this... but only temporarily. Every resume from sleep was a roll of the dice, and too often, explorer.exe would be in a bad state, affecting the taskbar, desktop, File Explorer, etc. Anyways, that's what brought me to this thread. Every time, I could temporarily fix the issue with a reboot or a restart of explorer.exe, which seems to point to a bug in explorer.exe.
I'm posting this in the hopes that:
a) someone from MSFT sees this and can direct it to the appropriate team to be fixed, and
b) maybe🤞 the unpin/repin of icons on the taskbar that I mentioned above will help someone else out there.
Hope this helps,
Dave
