S20 beta...

[Weth85]

Keyboard is glitchy today....typing and it's taking a few seconds to catch up and often freezing

This is a common problem in beta 2. So far my solution has been reducing transparency and blur and removing animations.
Have a look at my discussion thread called "UPDATED - 100% cpu usage"

Perfect thank you

Also getting this problem with my S20+ sometimes.

@Weth85,

Please, try to clear cache of the Samsung Keyboard app and then reboot your phone.

If that won't help, report the problem via the Samsung Members app attaching log files .
