Thanks for reporting.

I cannot reproduce this behavior. Can you share more detailed steps or a screen capture showing how to reproduce? Can you share image IDs for areas where the problem occurs?

[oscarlorentzon]

@willemarcel Does this problem still occur?

[willemarcel]

@oscarlorentzon I used mapillary for a long time session today both in mapillary.com and in osm.org and the errors didn't happen.

[willemarcel]

The problem occurred 2 times again, but every time I try to record my screen, the error didn't happen.

[oscarlorentzon]

OK, thanks for notifying. It would be great if you could share an image ID/link next time it happens. A video (with Firefox dev tools opened) would also help.

@willemarcel Can you make sure to open the developer tools in your browser the next time the error occurs and grab a screenshot of the console output? That would help with debugging.

Also, can you describe in more details the exact steps you take for the error to occur and provide an image ID? I can't seem to reproduce it.

This one happened in another session:

I have personally experienced this issue from time to time, but not recently.
