Rx2 Issues, please Help!!!

Hi everyone,

i have some Issues since last year May on my Rx2 it did not happen. so often before .but since a few months the became regular issues, it became a part of my life and its reaaly annoying. i play my set always in midi mode on my macbook pro. Firstable when i load a track in a deck, everything seems ok on Macbook but there is always 5-10 seconds delay until i see  Waveforms of the track on Rx2s screen. After 1-1,5 hours playing on Midi Mode i cant see any waveforms anymore on my rx2s screen, evertything seems and goes ok on my Macbook pro, it happens just on Rx2. Sometimes when i am loading a new Track in Deck, i see the id of previous track on the screen of Rx2 and also no waveforms, it plays, goes on but i cant see anything, no waveform , no track id no tone no info etc. 

Its all ok but there is a one more issue and its absolutly unacceptable, after 4th or 5th Hours of playing music  Rx2 is frozen, there comes an annoying tone out of Monitorboxes and no button doesnt works any more, if i dont do anythig it stays so untill i reboot the Rx2. 

Please can anyone help me to fix these Bugs??

I have the latest Updates on Rx2 and also latest Version of Rekordbox on my Macbook Pro.

Macbook Pro 15 TouchBar (2016) Intel Core i7 2,7Ghz, 16GB RAM, Radeon Pro 455 2GB, 256GB SSD, Mac OS Big Sur (same happens on Sierra). 

Here are 2 Videos of yesterday night.
