Very nice work, it's probably the first time we find something depending on
correct dirty rects handling in UpdateTexture().

This shouldn't be a hack, it's behavior we want to replicate. We want to test
how it works exactly (e.g. after multiple LockRect() calls should multiple
dirty rects be stored or just the union of the rects?) and then write a proper
implementation.
Actually there seem to be some relevant tests in Wine already (see
add_dirty_rect_test() in d3d9/tests/visual.c), hopefully they are a good
starting point for further work.

Interested? :)
