When using the Default Big font the Time label and Duration label both get cut off at the end in the DialogSeekBar
Appears in both Kodi 16 and 17
To reproduce switch font to Default Big, play video then pause.
I increased the width on both from 135 by just one point to 136 and it solved the ends being cut off but Duration now hangs a bit over the background popup. Not entirely sure how to tweak that.
