Is it our “graph” screen that is lagging? Are you using the mini viewer also, or just the main GlassWire “graph” screen?
Does installing this beta help? Try the GlassWire Windows 2.0.81 beta!
I don’t recall anyone else reporting this problem yet with a graph “lag”, but for some high resolution screens we made some changes/fixes in the beta that might solve this. If this beta doesn’t solve it for you then we know it’s a bug we should try to fix before our next 2.0 update.
