It’s just like fishing a “river” when still water start skimming like this and it can be difficult…..but
Just like a river, change your float, a slim version will just ride up, you have no weight to “get hold of” here don’t be afraid to go heavier and something with a “shoulder” on alternatively well over-shot the 0.30 to nail it down…. but then hold it up.
Yes line bites will be an issue and probably a few foul hookers but that’s the way it is….. no firm solution but change your float, go heavier, nail it down….and hold it up….
