I have 4 Gb. I've not noticed lyx using a lot of memory, except when it
crashes.
Does your PNG images contains a lot of white background and only some lines?
I would be better to give us maximum resolution in pixels of these images
and the number of colours used to store that files. PNG files can be
compressed by lossless algorithm, so files could be small for large areas of
single colour, but large uncompressed for displaying. The other possibility
is that one of your images has failed internal structure and QT (as far as I
remeber, bitmaps are handled by QT routines in LyX) become stupid trying to
display such image.
That is very much the kind of problem we'd seen before. (Pavel was the
first to notice it, I think.) The caching mechanism is such that it more
or less stores bitmaps of all those images, and the bitmaps can indeed
be real big, even if the file size is quite small.
So it seems pretty likely that 1.6.4 suffers from some version of this bug.
Cross-posting to devel.
