Kali linux on raspberry pi 3 is buggy

I just bought the raspberry pi 3 , I installed kali linux (for the pi 2/3) . So here is my problem , the windows are buggy sometimes you can drag them around sometimes you can't . The right click does not always work .

Also I installed teamviewer for the architecture armhf , it all goes well until I need to accept the EULA . I can't click on accept, can't drag the window around and it bugs all the rest when this window is open (can't click on other windows like my terminal).

I reinstalled kali but nothing changed .

I tried to google this issue but came out empty, thanks for reading .
