Got the same issue here on Kubuntu with when activating transparent background in Konsole with an AMD GPU (flickering of background between transparent and solid).
It only started happening when I switched to Wayland. X11 does not share the issue.
I managed to fix it in Konsole somehow by switching to another apperance theme in the profiles configuration (you might see there that, for some reason, Breeze is duplicated, which I suspect is what responsible for the flickering).
In my case I was using X11 when I posted this. I get flickering on both X11 and wayland and that's a bit ugh sometimes 🙃🙃
recommend posting to https://gitlab.freedesktop.org/drm/amd/ which is home to the issue tracker for AMD graphics on Linux.
There's plenty in there going back to 6 months+ sadly I don't think I can bring as much details as everyone's elses posted issues. It's a waiting game from here on :(
