The deepness of the open call graph is different. The 2nd shows more details inside of the getTextLayout_helper function.

I'm not sure how to do that - this is an excerpt of the heaviest stack trace.

I’ve changed the filter from „matches all“ to „matches any“ (?) and then I tried to locate examples of these.

The result is the 3rd image now.
