Disappearing graphics for wind and barometer

The wind circle and barometer arch randomly disappear on my weather display. The wind circle often flashes when wind information is updated. Sometimes it will stay on and other times it disappears. This is happening for both Rpi3 and Rpi4 models when connected to HDMI. I’ve tried several HDMI screens, monitors, and TVs. All do the same. Any ideas on how to fix this problem?

Might be related to the graphics memory split of the pi

see this topic for a solution :

Thank you. So far, I haven’t seen any issues with graphics after increasing GPU memory.
