"Issues" tab shows issues from a different file than the current one

Until Creator 6.0, the "Issues" tab showed issues only from the file that was being edited at the moment.

Creator 7.0 will frequently (but not always) show issues from a different file, which happens to be open at the moment, but not in the foreground.

I have not yet found a way to reproduce this consistently, but it happens very frequently. I will update this issue when I set a sequence of reproducing steps. Until then, I attach a screenshot. Notice that the problem file is not the one being edited.
