How much do you actually interact with dropbox's UI? I would think that most of the time you would just be using it through the standard file/directory interaction things (file browsers, shell, etc).
Configuring selective sync (which was a must since this was on a laptop with a relatively small SSD) is particularly excruciating, and I do need to tweak that from time to time when large folders are added. The window that pops up when you click the system tray icon also has the scaling issue, which is something that I do need to interact with on a daily basis. Luckily, it's not quite a bad as the selective sync configuration, but it's still pretty rough.
