Bug ID: 107889 Summary: colors are wrong on one screen with Radeon RX Vega M GL and Kernel 4.18 Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: mchehab@infradead.org
Created attachment 141508 --> https://bugs.freedesktop.org/attachment.cgi?id=141508&action=edit Picture with the 3 monitors. The colors at the center one are wrong
I have a 3 monitors setup on a NUC8i7HNK (with latest BIOS: 0049).
I'm currently using Kernel 4.17 + DRM patches for 4.18-rc1. Everything works OK. However, upgrading the Kernel to 4.18.5 (kernel-4.18.5-200.fc28.x86_64) causes that the center (and default) monitor to mangle colors. The same issue also happens with upstream Kernel 4.18 vanilla.
I'm enclosing a picture of what's happening there.
