Podcast cover art is missing on the iTunes store

Yes, something in Windows display settings. DPI scaling at anything other than 100%, or features for enlarged fonts have cause problems with iTunes on and off over the years. Seems like someone at Microsoft or Apple must keep making the same mistake.

The other factor that may impact on this is DPI scaling, but for other users who have recently reported the issue it seems patience has been the cure. You could report it to Feedback - iTunes - Apple in case there is something Apple need to do at their end.

Finally a good tip. The DPI solved it. If you have this problem, you need to go into display settings and change the scaling back to 100 % (assuming you, like me, had it set to something else).

Now, I will just have to buy myself a new pair of glasses to actually see the tiny covers and text...

Adobe actually made some applications do the same things. Even some Microsoft Office apps had to be updated because of new high def monitors (I think).

This is just plain stupid. In a world of hi-res 4K displays where no one can use 100% scaling else you need a microscope, something must have recently been broken in iTunes. Mine just started showing grey icons also, and this thread is relatively new, so I'm guessing someone broke something somewhere.

I find it hard to believe no one at Apple has 4K monitors running Windows to test their Windows software?

You may be able to adjust some form of compatibility mode so you can have a more reasonable font and icon size elsewhere without breaking iTunes.
