Interactive Before/After Wipe problem

The Interactive Before/After Wipe is a great feature and very useful for image comparisons however it now also creates a new problem because of the way it is linked to the Show Original mode.

Selecting the Show Original mode used to be a nice workaround for automatic re-rendering problems but that is no longer possible currently. For some filters it's not really much of a problem but for any that take a longer time to render it means the CPU is always high.

The manual preview update buttons Vladimir Golovin posted images for in this thread a while back would solve this however -

I hope the manual update feature is still going to happen and if it does that would make it possible to avoid this new problem and would also be a very useful option.
