New dirt artefacts appearing in all my documents
Hello
Today I started noticing that some weird white artifacts/pixels started appearing across my PSD documents. They also seems to adapt drop shadows from the artwork. But they do not disappear when I hide individual layers or effects, nor does the dirty drop shadow clutter disappear when I turn off all layer styles. Meaning it's super random. I worked in Photoshop all my life and have never come across something like this.
When I hide ALL layers it disappears with them but as I said above they still presist while hiding individual layers so it seems like a software rendering bug.

It's also happening to all my documents. Not only this one. I've tried mixing with the performance settings for my graphic card but to no use. Also tried flattening the smart objects, removing masks etc. and nothing helps. Restarted the computer also and still there.
Would be very thankful for any help.
