Description

Hello @almarklein

On opening a visualization, once you minimize it freezes the visualization once you maximize and the terminal shows a traceback shown below.

ERROR: Error in scheduler-task task:

ValueError: Physical size values must be positive.

This happened both on Windows and MacOS from my testing.

Winodws 11 and MacOS with m1.

This was fixed in pygfx/wgpu-py#788
