Yes, this is a known problem. I also think that the caching of images is the same \
problem Paul had. Unfortunately I see no way of disabling it via X11 command line \
:-(.

I guess it needs to be done in source, but it could hurt performance a bit ...

Yes, thats the same advice I would give. Disabling backing store on client might help \
with not image-related memory usage.
