So we can f= ind expert in that area to continue to triage. Your current report is case 2, s= o it can be replaced with=20 2. amd-drm-next-5.14-2021-05-12* with ip_block_mask=3D0x0ff, with Xorg and without 3D acceleration in daily use. I suggest you to execute your test plan in order 4->3->2->1. Thanks! James --=20 You may reply to this email to add a comment.
