Description
In VTM6.0rc1, SCIPU (JVET-O0050) is implemented for YUV444. It is not clear why SCIPU should be implemented in that case. In YUV444, the block size never goes down to 2x4, 4x2 and 2x2 so the problem stated in JVET-O0050 don't exist.
In addition, when both SCHIPU and palette mode are enabled, encoder & decoder crashes since local dual tree block is introduced in single tree slices, which mixes the joint and separated palette tables.
We suggest disabling SCIPU in YUV444. Below is the merge request for the fix:
