thanks for the quick answer millhouse. re PSU it's rather weird though as I never had any indication in the past, plus it's the pihut certified one, bundled with the rp3. i just rebooted and right after the rainbow screen i get the flash icon for a second then it disappears. as this was not happening before #302 or any other build before that I guess there are 2 options: 1) the readout is faulty or 2) the PSU just decided today to crap out on me. although Kodi is running fine 24/7 without any problems whatsoever (power wise).

reboot didn't change video calibration
shutting off, unplugging and rebooting did, though. had to recalibrate slightly after that.
also seemed to have lost some other settings, related to UI sounds, was silent before now default sounds are back active.

edit: i just checked the psu with my multimeter and the psu is fine (5.2v stable reading). on this second cold reboot then I was expecting to lose settings again but this time only the lower right corner was slightly changed and I had to make it larger again by a few pixel (not that you would notice but still the blue arrow was not at the exact same position as before the cold reboot), upper left and subtitle position (1025) was the same and no other settings were lost. weird.
