Thanks for reporting this. Which browsers was this tested with? Which PageCuration version and which MediaWiki version do you use?

I tested this with Internet Explorer 11, Microsoft Edge, Chrome, and Firefox, all on Wikipedia and all in Windows 10. They all show the "sticky blue" bug on the curation toolbar.

Special:NewPagesFeed is only available on English Wikipedia. :)

The icons are supposed to be all grey except the check mark (green). When you hover them, they turn blue and go back to the initial state. That's not the case.

The issue has been fixed (checked in betalabs).
@kostajh -I am wondering if the issue described below is a result of the fix:
"Go to the next page in the queue" button when clicked does not do anything and becomes inactive although there are more items on the list.

"Go to the next page in the queue" button when clicked does not do anything and becomes inactive although there are more items on the list.

I suspect that particular issue is related to T216674, let's follow up on that when T216674 is fixed.
