Huge lag when using mouse and keyboard on m10 with OTA14

If I connect bluetooth keyboard Logitech k810 with tablet m10 FHD (with OTA 14), everything works nice, but if I add bluetooth mouse Logitech MX anywhere 2, everything starts to lag. It only does that when both of them are connected at the same time.
And not only lag, when I type a text, I get additional letter, which are already pressed. Something like this:
I write "hello"
I get "hellllllllo"

If you need anything else, I will be glad to help.

Thanks
