Hi,

while opening a recording (as usual) pressing 9 - 7 to check cutting it is ok,
vdr already vanishes pressing just "9" (jump to end):

As I noticed, this happens on every forward jump (yellow, 3, 9)...

We are unable to reproduce this on our Haswell based setups, so you'll need to dig further on the driver segvaults. My first step would be upgrading Intel's vaapi driver to the same level as the used libva library (2.0.0 -> 2.1.0).

Still there:
kernel: [ 381.731713] vdr[4006] segfault at d8 ip 00007f714e5a4899 sp 00007f70cd6fb190 error 4 in libdrm_intel.so.1.0.0[7f714e59e000+22000]
runvdr: restarting VDR

Noticed, skinnopacity has some problems to display the << < || > >> icons, something like an old TV that lost Hsync (within the icon).

Will try kernel-update, hoping 4.14.24's USB3 issues have vanished.
