Container caching question

[i2399]

Hello,
I would like to improve the performance of a scrollable container by caching its sub-containers.
My framebuffer is in ARGB2222 mode.
My current problem is that I always get a Hardault for unaligned access even if my framebuffer is in a MPU region, as is the cache region.
Is there an issue with what I am trying to do? Is this not possible with ARGB2222 mode?

Thanks,
Ivan
