Give that most of the Sentient species in the Star Wars galaxy are non-Aquatic pretty much every MC80, with the possible exception of those attached to the Mon Calamari defense fleet would need to be drained unless they plan to force the non-Aquatic crewmembers to wear scuba suits while on duty.
And the problem with that would be?
If anything, I think this would really go hand in hand with the "designed for the Mon Cal physiology" bit, as it's easy to imagine that the Mon Cal eye is designed for excellent vision both in and out of water, and it's possible that the screens, whether 2D or low-level holo, might be designed for use underwater, and account for the refractive properties of the drink, and while the Mon Cal eye can easily adjust for this (similar to how a human eye can adjust for varying light levels), perhaps the eyes of the more landlubber species find that these displays, designed for underwater viewing, look rather warped/distorted/hazy/etc. In the newer, drier bridge.
