Grey Area on Lower Right Corner

Hey, Sorry for my English. I wonder if anyone else has this grey area on the lower right corner of the map area. It's mostly hidden with only greyed out arrows pointing up and down but when I point there with my mouse it hovers and becomes this grey space. It can't be dragged, it can't be used anyhow.  (Red markings made by me)

Hello Ignis Fatuus, I am sorry to hear that you are seeing this scrolling box.  It looks like it is the "Deck" scroll box. Check to see if you have any "Decks" shown/hidden in the 'Collections' tab. If you do, see if hiding/showing helps with removing this scrolling box. If it does not, then please try the troubleshooting steps listed below. Thanks! To rule out potential issues,  please carefully work through these steps of our guide to   Solving Technical Issues : Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome  and  Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable  all  add-ons/extensions. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through  Step 4 .  (Don't forget the complete Console Log!)
