Objects turn to black outlines and freeze during drag when zoomed above 800% (Beta 30.9.93)

Since updating to Illustrator Beta 30.9.93, I'm seeing an abnormal rendering behavior when moving objects at high zoom levels.

Steps to reproduce:

1. Open any document in Illustrator Beta 30.9.93

2. Zoom in beyond 800% (GPU rendering enabled)

3. Click and hold on any object to drag it

Expected result:

• While holding the click, the object moves in real time on screen, as usual.

Actual result:

• As soon as zoom exceeds 800%, the outlines of ALL objects on the artboard turn black.

• During the drag, the selected object appears frozen — no live preview of the movement.

• When releasing the mouse button, the object jumps to its new position (the move itself is applied correctly).

Behavior below 800%: everything works normally, with real-time drag preview.

Workaround: Switching to View > View Using CPU restores the normal real-time drag preview.

Environment:

• Illustrator Beta version: 30.9.93

• Dell Precision 5820 - Intel(R) Xeon(R) W-2245 CPU @ 3.90GHz (3.91 GHz) - RAM 32Gb

• Windows 11 Pro

• Nvidia RTX A4000 - 16Gb

• GPU Performance: enabled, Real-Time Drawing and Editing: enabled

This looks like the GPU rendering pipeline falling back to a degraded outline mode at high zoom, which disables the live drag preview.
