How to use cairooverlay to draw onto window

[Olivier Aubert]

Hello

Could you explain the context of the memory leak when using
rsvgoverlay ? On what time scale does it occur, do you update the SVG or
display it once, etc. It would be even better if you had some basic code
that exhibited this behaviour.

Regards,
Olivier
