Ok, fair enough.
I just compiled and ran your example with 4.8.5. I don't have 4.8.1

Looks like you have to upgrade to a newer Qt version. Which you really
should do anyway. 4.8.1 is *old*.

Hi Igor,
I do not know if this would suit your needs, but I would do this with a
pixmap representing the shaded rectangle. To resize it, you need to cut it
in nine parts (3x3) and stretch only the middle section.
Qt does a similar thing with QSS stylesheets and the border-image property
:
By the way, it would be nice to have a kind of QPainter::drawBorderImage

Have you tried running under Valgrind
to see if it has anything to say.

Nope, as I'm under windows now. But I will undust my valgrind dedicated
linux virtualbox for this... Hoping that the bug happens under linux, which
is far from sure.
I managed to trigger it with a timer and no user interaction, but it takes
more time to crash.
