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: [email protected]
Reporter: [email protected]
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
If additional information is needed please let me know.
