Visual lag using Kemper Remote (after update)!?

Hi, just asking if I imagine things, but I unpacked an Kemper setup with Remote just today and tested it out with the firmware it had on. I think it was 3.x.x But after doing the latest update on the system, it seemed like the remote got way slower it was before, hitting the switch only resulted in a visual change on the remote after a second. Fortunately the sound did change quick, so thats good, but does anyone else see the same behaviour or am I imagining things?
