IPR stops when editing Meshlight in component mode

[TheScope]

Steps to reproduce:
1. Create scene with some geometry and a meshlight.
2. Start the IPR. The scene should render correctly.
3. Select the meshlight and enter any componentmode.
4. Select any component of the meshlight.
5. The IPR turns black even though the icon indicates it is still rendering.

This happens with V-Ray 4.12.01.
This does not happen with V-Ray 4.04.03. In this version, the IPR updates immediately.

Thanks for the pointer, we'll look into this.

IPR in Next unfortunately remains very unreliable and will stop working randomly all the time.

Is this with Next or Next, Update 1?
If you can point us to some examples (possibly with steps to reproduce) it will help us fix bugs.
