Hi Carl.
It is still present in 2.14.2, but it seems to be related to my desktop resolution.
I have a 16:10 monitor, so running Windows at 1920x1200.
When setting my resolution to 1920x1080, the the white line is gone!
I just tried at different resolutions all the way from 1280x720 to 1920x1200, the result are this:
1280x720: OK
1280x768: OK
1280x800: OK
1280x960: White line
1280x1024: White line
1360x768: OK
1366x768: OK
1600x900: OK
1600x1024: White line
1600x1200: White line
1680x1050: White line
1768x992: OK
1920x1080: OK
1920x1200: White line
Hope this helps :)
Kind regards,
Jonathan
