I tried the other kernels but no luck. I tend to think the problem relates to memory going into swap (cache?). Any ideas on configuring? Swap size should be ok at 8GB.

Your swap is more than enough:
swap-1 type: partition
size: 11.72 GiB used: 0 KiB
Memory: 5.8 GiB used: 1.84 GiB (31.7%)
We can try to create a resume file, what's the output of this?
Also what happens if you suspend with this one?

From the lsbk command I get
├─sda3 swap 1 swapMX e75c0c7f-7643-4d87-9391-0c2360e101a5 [SWAP]
Unfortunately the command line suspend also leads to the same video problem.
Appreciate the help!

Ok, at least now we know that it's not a light-locker issue.
Code: Select all
echo RESUME=UUID=e75c0c7f-7643-4d87-9391-0c2360e101a5 | sudo tee /etc/initramfs-tools/conf.d/resume ; sudo update-initramfs -uk all
Reboot.
Though this may/may not solve this issue, no harm.

Ok, then , can you still use the terminal and do 1-2 things? Though the screen looks bad...
when that happens and let's see how it looks at that moment.

This is going to sound really odd, but lower your screen res to something under that 1680 and try the suspend.
If it works ok, then you may have an issue with the driver and refresh rate on that iMac.

This is really weird cause everything looks normal, drivers are ok and the res.. so, we can try just to turn off and on ..
When that happens try (if one doesn't work, go on with the next one):
Code: Select all
xrandr --display :0 --output LVDS --auto
Code: Select all
xrandr --output LVDS --off ; xrandr --output LVDS --auto
Code: Select all
xrandr --output LVDS --off ; sleep 1 ; xrandr --output LVDS --primary --mode 1680x1050 --rate 60
