I'm in FR265 Large, at v4.19B, this issue persist especially when the watch is in idle (AOD on). I saw it as well on Morning Report in some of the animations.
It persist constantly on my preferred watch face as well https://apps.garmin.com/en-US/apps/0f58becc-62d7-4150-9f81-5f59588f8792 (AOD on, screensaver mode).
Please confirm if this is something that you can fix via software update because my warranty in our country(Philippines) is limited (7 days, I believe and I only have til May 24). It's difficult to capture on a video but some user captured it quite well here https://imgur.com/a/X3F64Vm. Please get back to me ASAP. Thank you
