Console screen is not updated, but kmscon is working

System: Arch up to date
Installed: kmscon-patched-git as of today 9.0.0.r10.g20a2fc4-1, libtsm-patched-git 4.0.2.r17.gd66dd16-1

Symptome: The console is working, but the output is only updated when I switch between consoles or console/X. I can log in and type commands, but the screen is only updated after console switch.

I've got a similar problem, not sure if it's the same.
When I log in in TTY2 and run any command and then switch to TTY1, I see the entire output of TTY2. However, if I start typing, it randomly flashes between the TTY1 login and the TTY2 output. Worst of all, it shows the password I typed in login on TTY1 in the random flashes in TTY2.

Same goes for all other TTYs, they randomly flash with the content of the other consoles.

I'll try some more combinations, like turning off hardware acceleration and some other things, but I'm not sure if that'll fix it.

Should I open a new issue for this?
