Hello @ammachado Thank you for submitting the issue

Can you share a file that causes the error? It would be really helpful

ammachado commented 5 years ago

@kornilova-l Yes, for sure. How can I send you the file?

kornilova203 commented 5 years ago

You can send it to email ... Thank you!

ammachado commented 5 years ago

@kornilova-l, I've sent the file to you.

Hello @ammachado, Sorry for such a long response I could not reproduce the issue with FlameViewer v0.8.1 and with master branch version. Could you please confirm that the issue is still present? And also please check what version of plugin you use (to do so open Settings | Plugins, search for FlameViewer, the version will be below the name)

I refactored big part of FlameViewer so hopefully some old bugs will disappear in new version
