Lost transparenncy in many icons, background is black
I seem to have lost transparency for a number of icons on the "Windows 10"-style Start Menu. They now show against a black background. I've snipped a few screen shots here.
This happened after I rebooted yesterday for the Windows out-of-band patch. I don't know if that is actually related. I have another system that was also patched and isn't showing this behavior. I tried doing "refresh icons" from the right-click menu, and outright rebooting, but the problem persists. I also switched to the "Windows 11"-style menu and I can see the same thing on icons there, with some that feature transparency having a black background.
Other programs aren't showing this issue with the same icons. (Actual default Windows 10 Start menu, Directory Opus, ...)
