I've been trying to solve this for quite some time- nothing I try appears to work.
The problem is none of the icons on my desktop are being displayed with their alpha channel. A picture is worth a thousand words, though:
Actions I've taken:
used tweakui to rebuild the icon cache
deleted all non-shortcut files from desktop folder.
deleted shelliconcache
changed the display resolution and colours back and forth between different settings...
the problem persists, however. Strangely, everything else- start menus, explorer windows, etc, shows icons with their proper alpha intact.
Any suggestions?
Alpha icons still
