Tvheadend

Hi,

for both OSMC and libreelec with Kodi 18 and tvheadend plugin 4.4.17 or 4.4.16, if omxplayer hardware acceleration is turned on, the first seconds of a live tv are stuttering.
If you want to switch channels it works exactly once. Further attemps to switch the channel (up or down) do nothing.
For the first switch, the time shown at the footer (instead e.g. 30:00 of 90:00, known by EPG) is for maybe a second "00:00", then "-00:06".

If omx player hardware acc. is turned off, everything (zapping up and down) works fine.

This did not happen with kodi 17.6.

one can reproduce this very easily:
setup a new librelec 9.0.1 with kodi 18 on a rpi3 and just install and configure tvheadend (for me: tvheadend server on debian with sat>ip with AVM Fritzbox 6490 sat>ip Server).
play a station and switch up or down - working. No stuttering at the beginning.
Turn on omx player hardware acceleration - described issues appear.

If this is not the place to report, can one advise where to report?
