Any pointers on how paintCompression works... Dictionary says: "When an
image is changed with a paint tool, it is recompressed the next time you
leave the card it's on". Is this also true if imageData was directly
updated - i.e. image gets compressed next time I leave the card it is
on, isn't it? Or is image recompressed each time its imageData gets
updated ? If so, likely RLE is the fastest method to choose or is it
possible to disable paintCompression for images to get  more speed for
image updates or RLE is the only option to go ? Or if imageData and not
the actual image is what is displayed on screen, then may
paintCompression have no impact on how fast imageData is being redrawn.

See Bugzilla 5113 and my accompanying test stack <http://www.sanke.org/Software/TestStackPaintcompression.zip>.

Handling imagedata can be up to 12 times slower with paintcompression set to PNG than to RLE.
