One fix for bug [#33785] compositor is (unnecessarily?) slow

Added additional buffers - new subtree - for groupnodes.
One needs to be aware of how groupnodes should be created. 
Having translate & scale nodes, with the translate inside the groupnode and the scale node outside, causes artefacts.
Both should be inside or outside the groupnode. Same holds for other distort nodes.
