Not when watching F1 but I get this problem too for the football, it's been like it for a while. I have spoken to Sky Support and they say it's a Virgin problem. My main device is a Samsung A8, the problem happens when the match contains timeline and stats (see screenshot) which is most games these days. The issue is the same on a Nexus 7 too, however it is OK on my phone (Samsung A40). I have also tried it with someone else's Virgin account and the problem is the same.
I have attached screen shots so you can see the issue:
