I have been chasing a problem for the last few days, where certain taskbar icons were getting corrupted every day. I pin my most used ones on there, so I have 28 in total. After I booted up, all my icons would go white, then gradually, they would show their normal icon.

Then certain icons stopped showing properly and reverted to the default icon. When I looked through my Start Menu, several other icons were the same. An iconcache.db rebuild solved it but I was having to do it every day, which whilst quick, was extremely annoying.

I have just uninstalled DisplayFusion and all my icons now appear instantly, all correct... no intermediate white icons. As a test cure, I had write protected my iconcache.db file and sure enough, this morning that file was untouched but my icons were corrupt. So I knew it had to be something outside that file. That makes me wonder if DisplayFusion is doing some undisclosed icon caching.

Is this something the devs are aware of, or have heard of before? I disable all functionality apart from wallpaper changing, so am not quite sure why (if it really is the case) that DisplayFusion was doing anything taskbar related. I'm going to reinstall later but I just thought I would post the question in case it is either a known issue, or an issue that hasn't been spotted before.

I've just reinstalled DF, changed that setting, did a reboot and immediately got the problem back.

I have attached two images showing the problem symptoms. The icons all appear at first, then the desktop flashes, 90% of the taskbar icons turn white and then they gradually return to normal. Apart from those that turn to the default windows icon.

The interesting thing is, I didn't do a settings clear when I uninstalled, so could this be picking up a corrupt cache from somewhere in the DF files?

Interestingly, after a secondrestart via my Windows 10 install (my development OS is Windows 7 and I dual-boot Windows 10 as a dumping ground and test bed), the icons have stopped flashing and all icons are as they should be, both taskbar and Start Menu.

I'll keep my eye on things over the next day or so and post back if anything changes.

Okay, booted up today and the icons are missing again.

Edit: A subsequent restart has put them back again... I'm beginning to wonder if this isn't like my last problem that just happened to temporarily fix itself after uninstalling DF but it was ultimately just a coincidence and it ended up not being DF related.

I will update as I find more info but for the meantime, consider this problem on-hold... sorry.

So I was right... this was another coincidence that just happened to disappear for the period of time I had removed DF. Turned out to be registry corruption that seemed to be randomly pointing shortcuts at wrong locations, resulting in the icons going AWOL.

Sorry for the confusion... again. I'm just so wrapped up coding something that was directly using the programmes associated with those icons, it seems like I am jumping to the first conclusion, rather than the correct one.

My apologies...
