I have been using PyCharm in Linux for several years now and this behavior is relatively recent. Since the last update (PyCharm 2019.2) I have experienced an issue where by when I type in certain letters, they instantly disapear and the cursor backs up one space. It seems to happen with vowels mostly but some consonants as well. I suspect I have some specific input mode(?) or editor plugin enabled, but I have looked and I cannot find any setting or plugin that seems to be responsible. I am hoping that someone can enlighten me as to what maybe causing this. It makes it impossible to be productive when creating python code.
Example: I want to type in the line "with open("somefile.txt", "rw") as inputfile:"
Results: Type 'w'. w appears in the editor. Type 'i'. i appears then immediately disappears and the cursor backs up a space! If I type the same character twice in row it will stay, but then it happens two or three characters later.
