VFB flickering

[Volker]

Flickering occurs repeatedly with VFB 2.0 even when VFB (legacy) is used. C4D 2025.3.2, Corona 13, Win 11, RTX4070TI, RTX4080 Super. We have checked all possible settings and also removed special plugins. However, the flickering still occurs.

Hi, so it happens with both VFB2 and the legacy VFB?
In the video it looks like the rendering is starting and stopping repeatedly. In what exact situation does it happen? All the time whenever you just open the VFB?

[Volker]

This happens after I start the renderer. If C4D is closed and restarted, the first interactive rendering works. However, as soon as it restarts due to changes in the scene, the renderer starts and stops.

The same effect also occurs with VFB legacy.

Is it possible to share a screen recording either here or in a ticket so we can understand this flicker better?
