Lesson 6 frameBuffer.s Alignment Inconsistency

In Lesson 6 part 4 (My Dearest Graphics Processor), it mentions the importance of using .align 4 such that the lower 4 bits are 0s. The solution uses .align 12 as page alignment, justified for correct communication with the GPU. Is this a mistake?

.align 4 is correct and sufficient. .align 12 came from some of my early experiments when I didn't understand the GPU caching behaviour. The solution should be corrected, not the tutorial text. I'll leave this issue open as a reminder to do that.

The bug is still open which is causing the confusion in understanding alignment the concept.
