I think I spotted the cause of that and hopefully fixed it in https://patchwork.freedesktop.org/patch/97600/ Götz, can you try following patch, it should solve your issue: https://patchwork.freedesktop.org/patch/102122/ (serie is : https://patchwork.freedesktop.org/series/10444/) Believed fixed commit 0d9bdd886f295b62c254a99da4153e7d287adb12 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Aug 4 07:52:37 2016 +0100 drm/i915: Convert intel_overlay to request tracking intel_overlay already tracks its last flip request, along with action to take after its completion. Refactor intel_overlay to reuse the common i915_gem_active tracker. |
