Help! What should I do about the vertical jagged stripes when loading a scene? #339

I'm experiencing a serious issue when loading a PLY scene in SPARK2.0 — large portions of the scene environment appear with vertical jagged misalignments. Strangely, some areas of the scene render perfectly fine, while most of the scene exhibits these vertical jagged artifacts. Could you please help me figure out how to diagnose, pinpoint, and resolve this problem? It's quite urgent. Thank you. I've attached two comparison images for your reference.‌

‌Background context: My scene data was produced using the PortalCam from XGRIDS(其域创新), processed through their LCC Studio tool, capturing an on-site scan of a planned venue. The device's scanning head uses a multi-line laser scanner. When we open the same PLY file in other third-party software, these jagged misalignments do not appear. The file size is approximately 640 MB, containing around 9.7 million Gaussian points.
