I am not sure whether this is relevant, even though I have FramebufferCompression set to "no" there is periodicall blinking (I am not sure whether it is exactly regular, but it feels like every minute or so) when whole display blinks for a fraction of second like when visual-bell is set on (but there is no reason to beel set off).
