Hi there,

AMD Radeon RX 480.
Linux 5.0.13
Full HD screen with hdmi
Archlinux KDE Xorg

It's a problem I had noticed for some time, but couldn't figure out what was
triggering it. Sometimes after screen mode change there is random green lines
appearing on the screen (random location, but about one third of the bottom of
the screen).

It seems i can replicate it on my system by changing the resolution in the
system settings from 1920x1080 to 1280x1024.

When going back to full hd, the green lines sometimes remain. Shutting down the
screen and resuming it helps (but if still at 1280x1024, the lines remain).

The random line disappear when the screen doesn't refresh (cursor not moving,
nothing drawing on the background).

No particular message appear in the dmesg after changing resolution.

I assume this is not enough, please indicate me what would help.

Can you get a picture or video of the lines?  Please attach your dmesg output
and xorg log (if using X).

amdgpu.dc=0 makes things worse.

http://dev.ipol.im/~adavy/green_lines2.mp4

As you can see, instead of a few green lines, there are instead a few full bad
frames.
