Effort has been underway to make the Caret source code compatible with the Ubuntu way of doing things. As David mentions, we are planning to release an updated version of Caret very soon. An update for Ubuntu should be available at the time or shortly thereafter.
I do not know what would cause the fonts to be scaled improperly. A Google search for "ubuntu qt font too large" indicates the issue has occurred with other applications. On other types of Linuxes, there have been buggy versions of the FreeType library but Caret usually crashes in this case. You may be able to specify a font as a parameter to caret5: -fn or -font font, defines the application font. The font should be specified using an X logical font description.
