There is a bug in the streamer configuration of the unfold and fold modes. It is not able to handle partial tiles in W-dimensions after the very first tile (> 64). However, in MobileViT where these operations occur, W is at most 32.
The problem is, that the strides of d4 would need to be irregular to handle this case. It could potentially be split in SW HAL into multiple operations.
This is how the streamers are configured (65x4x66, unfold):
