Draftsight screen frozen

DS 2019 freezes when during an operation, the mouse flies over a block with a lot of entities.

I already tried compatibility with windows 7 and “Use dashed entity selection highlighting” option, but none of them works. I personally think that the problem is linked with the “object snap” when a block has a lot of elements.

Does anyone have a clue of how to solve this issue?

Thank you in advance,
