Jerky map scrolling on Fenix 6 Pro

Hi folks

I have a Fenix 6 Pro and have noticed a bit of a glitch with it.

When I'm moving fairly fast e.g. cycling and am recording an activity and have the map screen displayed, the map doesn't scroll smoothly across the screen.  Rather, it seems to jump forward a few pixels then jumps back a few pixels, almost like it's correcting itself, before then jumping forward a few pixels / back a few again etc. etc..  It doesn't scroll smoothly across the screen under the location marker, but rather the map moves across the screen in a series of jerky jumps.  It's a bit annoying.  I don't see it when I'm moving more slowly e.g. walking.

I have recently updated the Firmware to the latest version (27.0.0) and turned off all map layers except the one I want, but these changes seem to have made the problem worse...

Has anybody else experienced / solved this issue?  If so, grateful for any tips.

Many thanks.

Ben
