I have the same problem, but what I can add to this bug report is it happens
when my Monitor is using the Deep Sleep function, which is like a standby
function. In this mode the OS needs do a power cycle on video adapter to wake
the monitor up. I have tried just turn off the option but was in vain, because
I reinstalled the system(moved to f2fs on a NVME SSD) few day ago and forgot to
add the kernel instruction on the bootloader for optimize power on my AMD RDNA2
(amdgpu.aspm=1). This is the 3rd day I test it and the problem can be avoided
doing this.
Neither Kernel 5.11.x to 5.13.x can wake up the monitor in this state, which
covers all new AMD Cards (Big Navi / RX 6000 / Navi 2x / RDNA2)), at least not
using open source drivers. On Windows it work.
An issue still related is soon after I unlock the session I can notice all my
KDE Apps reside to another shape, Konsole, Dolphin, Konversation are examples.
My theory is when the machine enters in a state of "standby"(not hibernating or
suspended) the video adapter sleep, and Wayland can't find any available
display to handle the session to unlock the screen, also resizing to small
resolution.
Maybe what we need in here is to a dummy video adapter to exist and handle
stuff while none are available, changing back to the first available adapter
after.
Just for observation, using X.Org this issue of unlocking session doesn't
happen, the other however still exist.
