Help with pinning down screen tearing issue topic

Hi!

I'd like to try eliminate the screen tearing issue in mk kernel, but i need your help with that. The problem is - I don't have it ;) and by looking at the code and commits hinted by other devs it can't find anything useful.

If you can, try to describe in what combinations of Rom/kernel/anything it occurs and in what it does not.

But most valuable would be the reports when you just upgraded something to a different version and it made the problem appear our disappear - it's the change that it's important, not the "direction" (better/worse)

And check what type of LCD do you have in /sys/bus/mcde_bus/devices/. Report if it's different than
pri_lcd_s6e63m0.0
