exportgraphics causing strange messages in terminal only for Compiled version of App

When running my app after it has been compiled, exportgraphics calls seem to cause the following messages (or similar) to output in the terminal window:

<</ID[<05208558C807F1784140FF8D8426A497><05208558C807F1784140FF8D8426A497>]/Info 1 0 R/Root 40 0 R/Size 41>>

These messages are not to my knowledge actually causing any failures within the program, as the plots still export to the pdf and seem the same as when generated outisde of the compiled version. But similar messages post every time exportgraphics is called. If remove the exportgraphics calls from the code and nothing else no messages appear.

These messages do not appear when running the app from App Designer as a .mlapp file.

Some further testing reveals that the above messages do not appear for the first exportgraphics call, but does appear for all subsequent calls with the "fixing references" numbers called out increasing for each call.

Hi @Austin B,

Could you share the ".mlapp" file so that I can reproduce the issue?

If I did I think I wouldn't have a job for much longer unfortunately... I can tell you though that it is only exporting relatively simple 2D vectorized plots to a pdf, and the compiled program gives no complaints when the exportgraphics calls are commented out.

This issue was fixed in R2024a.

The problem occurred when setting append to true in exportgraphics.
