Constant crashes on XIV

[Kirika-]

Did you ever have this issue and it fixed it? Or

Not specifically with FF14, but I have worked on several PC systems were the user had Rainmaker overlay running and it caused issues with other programs that used Dx for displaying content.
Again, it wasn't consistent, and not every Dx display program was effected, but it happened more if the Dx versions were different between Rainmaker and the program in question.
