The Tkinter.PhotoImage class leaks memory with each change of the 'data' Attribute due to Image calling tk._createbytearray, which allocates memory, but never frees it. The offending method is in the TkApp class, _createbytearray(). |

Thanks for the report David. Feel free to attach reproducible script if any that might trigger this. I am adding Serhiy who might have a better understanding of this. Relevant issue where _createbytearray was added : issue21580 . |

Attached please find a Python script that demonstrates the bug.

Here is a simpler reproducer. Actually the problem was not in _createbytearray(), but in converting the Python wrapper around Tcl_Obj into Tcl_Obj. _createbytearray() just exposed it. The leak exists in Python 3 too, but it is hard to reproduce it. |
