Public bug reported:
Hello,
This problem happening only on Kernel 5.13.0-21, Linux Mint 20.2 Uma. I am
facing trouble with suspending laptop while closing lid on my laptop. Opening
lid and waking up laptop from suspension lead to screen granulation, see
attached photo. On other kernel is no problem. Here are spec about my laptop.
