Thought M$ was the worst. In VisualStudio 2008 they introduced a really annoying bug that in environments that had non-English IMEs installed, when there was a compilation error, the default IME would be invoked, and of course, when you tried to fix the error, what you typed would make nonsense to the compiler. Contacted M$, they promised thatit would be fixed in VS2008 SP1. But the fact was they never made it until some versions of VS2016. When it was fixed, those IMEs had been removed from my dev envs for ages.
