epix2 pro black screen

has anybody noticed that with CIQ watchfaces epix2 pro goes black every now and then, and seems to go black also when returning from e.g. messages/notification and the timeout occures?
with a 5 button watch I can replicate the problem by pressing the light button, on/off a couple of times a little bit slower so that the flashlight will not activate. It's like the time just before the light comes on. Screen goes blank, don't know if it is framework related, a new version just arrived on my watch...
