I've noticed as of 7th July 2017 that the clock on the Pantheon greeter is misaligned to the right of the screen (after updating). At 8:30 in the morning I noticed that the 'M' in 'AM' was cut off - this is on a 1920x1080 screen. If this helps, I have the text size set to 'Large' in the system settings.
EDIT: This seems to happen regardless of resolution, have now noticed this on my desktop with 1360x768 screen. This has not been updated for roughly three/four days.
