I have Grafana 6.7 running on Windows 10 Pro Version 1903 OS Build 18362.720. I’m using Chrome (Version 80.0.3987.149 (Official Build) (64-bit)) to access a Grafana server on my local network. After days of problem-free operation, I see this visual anomaly on some panels.
I also see this instance of Grafana running a LOT slower than the other one on my system. I have two instances of Chrome each accessing one dashboard. The one with the blurry text is the slow one and it is also in full screen with no other tabs open. If I edit the panel, the text shown in the edit session is also blurry. As you can see, not all panels are blurry. Of the two that are blurry, one is a duplicate of the other.
