Bug ID: 108941 Summary: Enabling PP_OVERDRIVE_MASK with dual monitors causes artifacting Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: boukehaarsma23@gmail.com
Steps to reproduce:
1) Have dual monitors 2) Enable PP_OVERDRIVE_MASK by flipping the appropriate bit in amdgpu.ppfeaturemask. (For my configuration I used: 0xfffd7fff) 3) See artifacting.
When using default featuremask, or when using a single monitor with the overdrive bit enabled behaves correctly. I heard multiple people who have the same issue, so it does not seem related to my setup.
Setup: RX480 Linux 4.20-rc5
