Not necessarily the problem, no, unless it increases over time and never
decreases... The values do not seem out of proportions either, I mean, I can
get higher pixmap usage opening a few documents in LibreOffice here as well...

I'm just trying to figure if something is leaking, because maybe we look in the
wrong place, fixing the root cause of GL_OUT_OF_MEMORY might be more efficient
than trying to deal with the aftermaths.
