Rss Ticker often not loading right

Xibo Version : 2.2.1
Server : Ubuntu
Docker : No
Player OS : Windows 10
Player version : windows 2 R201-201

Screenshot of the problem

I have a RSS-Ticker in my screenlayout that often loads like in the screenshot. It has a white layer over the ticker so it looks like it stopped loading the RSS-feed. But when I reboot the computer/Screen it loads correct. I have no idea what causes this.

The background of the RSS-Feed should be black and the text of the feed should be white.
