Cursor and UI freezes while GPU switching

Hi.


I have MacBook Pro 16" with clean installed latest Catalina 10.15.2

When the GPU switches the UI and cursor are freezing on half a second.

I recorded a short video which demonstrates the issue. Please refer to https://youtu.be/5JdMOlFiD0U

Also i note that the GPU time is very large - 600 hours and it sigtly grow after each switching from Radeon Pro 5500M to iGPU.


Think it not normal. Is there a fixes or it is a known issue?

MacBook Pro 16", macOS 10.15

Thank you for the advice.
I have tried. It does not help at all.

I tried the following:
* reset SMC
* reset NMRAM/PRAM
* reinstall MacOS



 To trouble shoot further you can:


  Try a SafeBoot https://support.apple.com/en-us/HT201262


  Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache,  etc.  Login and test. Reboot and test.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode. 


 

  Test issue in another user (or guest user) account  https://support.apple.com/en-us/HT204443

  This will tell you if it a universal issue or isolated to your user/admin account.

I have tried SafeBoot. In safe move the MacOS works with the High Perf gpu only. The checkbox does change anything.


Also I have created a new user. And try to reproduce the issue.

The freezes stay much shorter. It stay slightly noticeable.

The GPU time of the WindowServer process grows same as on my main user.


I suspect the Android Studio application because this app is the first installed app after MacOS on my Mac.


Is there a way to temporary disable .kext Extensions?


I want try to disable the following:
