If you start LO with VCL_DOUBLEBUFFERING_FORCE_ENABLE, then VCL-level double-buffering is enabled globally. We know that currently it works in Writer, but e.g. not in Calc. It would be good if there would be a way so that applications can signal if they support double-buffering: then this could be enabled for applications where we know that it works ATM without breaking others.
