What does not
Moving widgets around (i.e. structs widget to the left hand side) crashes Xorg.
Fonts render awfully, not the way they do on Windows and not the way they render in the rest of Linux. This makes working with anything other than Windows bitmap fonts (only FON format for those works in Wine, no Unicode support) very challenging, because letters are so thin and blurry you can barely see them. This applies both to Windows-specific (msttcorefonts) and regular fonts.
Some standard fonts (i.e. Tahoma) and point sizes used by the Windows UI render OK, but letters end up smaller than in Windows, making them harder to see. Changing DPI or point sizes makes them as bad as all other fonts. Playing with ClearType registry settings and fontconfig options for hinting doesn't help, just results in variations of very poor rendering.
Global xrefs take about 3 times as long as they do on native versions of IDA.
What was not tested
Most of the functionality seems to work, it's the things that don't that make it unfit for full time work.
You can use it for a quick check of something without dual booting/starting a VM/buying a Linux license, but not for getting actual work done.
Linux-native versions of IDA don't suffer from problems listed here; they both work and look just as good or better than on Windows.
