Why do masked layers look differently?

When it comes to masking the advice is always "press ctrl+R to make sure it look correctly."
Is there a special reason why the canvas and the rendered view doesn't look the same?

Processor power and speed.

Variations in graphics card brands/models and drivers can make the 'realtime' preview differ from system to system.
When you press ctrl + r, you're rendering through the CPU which is the only consistent and accurate way to see the final result...but at the expense of speed of course.

In my experience, discrepancies in the canvas preview and render only happen when you have nested child layers, who are themselves adding or subtracting from each others masking under a parent group (or similar):
TOP GROUP WITH MASKING
- VECTOR TO BE MASKED
----subgroup vector
----subgroup mask
- GROUP MASK
----group mask vector
----group mask mask
My (probably naive) view is that this is an (undoubtedly extremely complex) bug. It's something we've been mentioning for a long time and I'm sure it's being looked at, but I can't imagine it's a variation in hardware issue...
