In most cases, the font is readable in the Linux version of Crossover Games 7.1.0. I do know that some of the tooltips are complete garbage, but that was introduced with version 7.1.0. In earlier versions, the tooltip text is at least partially legible. The other text is rendered properly, though it doesn't render line breaks properly.
As for the crashes, they seem to be random in the circumstances that cause them, but the crashes can be replicated if it occurs right after you save (on the same turn).
I rated it Bronze, because it seems to crash more often in the newer version, but it could just be bad luck.
