Screen gets torn or broken each time moving the mouse on TigerLake with newest Mesa driver installed
Issue overview: On TigerLake-UP4, I have installed Ubuntu 20.04 and have updated kernel to 5.7. I also install the newest graphic driver. But when I start it and as long as I move the mouse, the screen gets torn or broken into different frames. With kernel 5.7.0~rc1, I have tried drm-tip several days ago, which do not fix this issue.
Steps to reproduce the issue: Get a TigerLake hareware, install Ubuntu 20.04, update to kernel 5.7, update graphic driver with "sudo add-apt-repository ppa:oibaf/graphics-drivers". Then just boot it, when you try to do some operations, the screen comes to abnormal.
How often: always
