I'm not using a s10 line up @SevenMentor
But when my Note 10+ 5G is sat on my Samsung Duo Charger or Samsung Fast Charging Wireless Desktop stand I'm still able to use the phones screen without any slow down wether it's normal or fast charging.
Are you using an official Samsung Wireless stand / pad or a 3rd party option ?

Same here - drives me mad. I have two different wireless chargers and both the same.
seems worse since I fitted a screen protector (tho I appreciate that should have nothing to do with it).
phone works 100% when wired charging or in use normally.
I have the same on my S10+ (Exynos version) with Tempered Glass screen protector (UV cured glue). The problem dissaperas if I increase the touch responsivness in the phone settings. I didn't test it without the protective glass. The touch ID works fine without increasing the touch responsivness.
there is no screen protector on my s20+, and i have tried the increased sensitivity option, it didnt improve my issue at all. i feel the issue comes from interference between the wireless charging coil and the touch screen. the touch response cuts out overy couple seconds only when on the wireless charger, problem disappears immediatly when taken off the charger. i previously had an s8+ and did not have this issue.
