[Bug 48887] Re: Zooming/Text functions cause 100% CPU Utilization & possible memory leak?

[Klaus Stengel]

I experience the same problem. I did some analysis with valgrind and
noticed that the problem isn't dia itself, but the text-layout library
'libpango'. On every redraw event some pieces of font information are
gathered by that library, but won't be cleaned up again so that dia (and
any other program that uses certain functions of libpango) takes more
and more memory until it has to be killed because there is no more space
left ( so called "memory leak"). This explains the OOMs the original
poster experienced and why it only happens when text objects are
involved.
