A small regression has been introduced around the version 2.3.0, that is visible only when you display an album on a mobile device with lower resolution than today's standard (e.g. 1280x720 instead of 1920x1080 pixels).
It looks like the left and right margins to display a comment versus the edge of the image has been increased a lot, apparently up to 160 pixels. This adds to the margin of the image itself versus the edge of the screen (32 pixels).
This means that on a 1280x720 pixels screen, when you hold your device vertically, the text of your comment is now displayed on a width of:
720 - 2*160 - 2*32 = 336 pixels only ... less than half of your screen!
Thus your comment text is now displayed on 4 lines instead of 2 earlier (see the attached mobile screenshot).
This margin of 160 pixels is hard-coded; the solution to this would be to let the user configure this margin manually from the skin settings; just leave the 160 pixels by default, we would be able to reduce it when needed.
