Bug ID: 108020
Summary: Screen artifacting with 4.18+ kernels on AMD Radeon
Vega 64 & 1440p 120hz+ monitors
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: mokurai82@gmail.com
I'm experiencing some interlacing on the right side of the screen of my 1440p
144hz monitor when using 4.18+ kernels and setting the monitor to 120+ hz It
works fine with 100hz and lower, or older kernels, which seems to indicate some
displayport bandwidth issue/regression. This happens regardless of the distro
or mesa version. I'm using an RX Vega 64 with the opensource driver.

This is likely fixed. It may be worth testing the amd-staging-drm-next kernel
from:
https://cgit.freedesktop.org/~agd5f/linux/
or applying the proposed patch from the bug report at:
https://bugzilla.kernel.org/show_bug.cgi?id=201067
Please let me know if you're seeing an issue with either of these.

Yes it is probably the same bug. It's a right-most vertical interlaced line.
I'm currently experiencing this bug in the newest ubuntu mainline kernel
(4.19-rc5). [It's not an issue on 4.18.8 kernel] I'm relatively inexperienced,
Applying kernel patches seems a little difficult for me. I only know how to
install mainline kernels from ukuu or .deb files. I can try if someone links me
clear instructions. Thank You for Your time and help. I hope this will be fixed
in future Linux kernel versions.
