Thats a broadcasting issue on Eurosport's 4k feed.
Its happening across platforms, so a Eurosport issue their end.
If you like Tennis, rather than watching on the Eurosport channel, even with the 4k option.
Open the Discovery+ app (free to Sky customers) on your Sky Stream.
It has multiple live matches to watch.
You can choose different languages and Ambient Sound.
The trick play is excellent, with a watch from start and selected timeline events during the matches.
Full match replays too.
