Kodi 18 Alpha PVR h264 encrypted playback issue

I testing Kodi 18 Alpha and have issues with the h264 playback.

Systeminfos:

Hardware: Odroid XU4 (Armv7 hf)

  • Samsung Exynos5422 Cortex™-A15 2Ghz and Cortex™-A7 Octa core CPUs
  • Mali-T628 MP6(OpenGL ES 3.1/2.0/1.1 and OpenCL 1.2 Full profile)
  • 2Gbyte LPDDR3 RAM PoP stacked

Software:

  • Kernel: 4.9.18+
  • OS: Debian Stretch
  • WM: Gnome 3.22 (Wayland)
  • Kodi 18 Alpha Waylandbuild from Kellermann (https://github.com/MaxKellermann/xbmc)
  • TVHeadend 4.1-2490~g2d90cd681-dirty
  • Oscam: 1.20-unstable_svn Build: r11380

IMPORTANT: everything is running inside wayland and on the same device

Problem:

Playback from encyrpted pvr (german hd-tv (h264/1080p) Provider: vodaphone) has many framedrops and unsync audio/video
Playback from harddrive or unencyrpted pvr running without problems in h264.
Same problem if using vdr as backend
