the current renderer implementation, (exact reason not yet identified) suffers from significant frame drop if blend_mode is set to normal (or other then pass-through) this is somewhat expected, but the frame drop is absolutely significant, almost unreasonably.

• 10 nodes, basic shape pass-through => 120fps, ok.
• 10 nodes, basic shape normal => 10fps, terrible.

Need to investigate, identify if tile caching is the only solution or has other approach
(but likely because of some obvious mistake in the pipeline)
