@Daniel Vello + Blend2D would be the most powerful combination available right now. It would be amazing if these could be integrated into VS. I downloaded and tested two applications these past two days: Affinity and VectorCraft. Both are noticeably faster than VS. Especially VectorCraft — even as open-source software, it outperforms Affinity in speed. Overall, VS still has substantial room for performance improvement. I hope to get an extremely smooth experience in version 1.4.

@Raaskot I have tested your file, and the rotation handles work fine on my end. The issue is likely with your workspace file. Send your workspace file and settings configuration file to the developer, and they will fix the problem based on your case.
