Hello,

I am experiencing a zoom lag issue with DraftSight 2026 on Mac and would like to report it in case it is a known bug.

Context: I am currently evaluating DraftSight 2026 as a replacement for AutoCAD 2024, and this issue is affecting my ability to make that transition.

Setup:
- Mac Mini M4
- macOS (Tahoe 26.5)
- DraftSight 2026 ARM64 (native Apple Silicon build)
- Logitech MX Master 3 mouse with Logi Options+

Issue:
Zooming with the mouse wheel is sluggish and unresponsive — the wheel can rotate several notches before the zoom actually updates on screen. It feels like the input events are being buffered or delayed before the viewport reacts.

Troubleshooting already performed:
- Disabled Smooth Scrolling in Logi Options+
- Disabled SmartShift in Logi Options+
- Disabled Animated Zoom in DraftSight preferences
- Confirmed Visual Style is set to 2D Wireframe
- Confirmed the build is ARM64 native (not running under Rosetta 2)

None of the above resolved the issue.

Is this a known issue with DraftSight 2026 on Apple Silicon? Is there a workaround or a fix planned for an upcoming Service Pack?

Thank you.
