Large memory leak when "Performance Overlay" is shown

[panmarco83]

As soon as the PO is visible (toggled with '\'), the system memory starts filling up

The two places I'd look first would be here:

janus/src/game.cpp

Line 2804 in 3f4e5e1

else if (show_position_mode) {

janus/src/game.cpp

Line 2981 in 3f4e5e1

else if (show_position_mode) {

Most memory profiling tools I've used previously let you snapshot memory in one frame, snapshot another frame, then compare them. The delta will show you the leak without much debugging required.

Thank you!

Ah, I have earlier done some testing on these sections and unfortunately deleted my changes, but I didn't find a definitive reason to what was causing the leak as far as I can remember.
