What kind of error is this? Licht?

[d515]

Can someone explain this to me…?
I just added a few light sources and got this result!

I don’t think it’s a memory or hardware problem…

I’m using an RTX 4090
with 128GB RAM and a 4TB hard drive with 2.7TB of free space.
CPU: Intel(R) Core™ I7-7820X CPU@3.60GHZ

Can anyone please help me with this?

Hi @d515

Sorry to hear you’re running into this. Could you please provide a bit more detail about what happened prior to this issue?

Screen glitching after adding lights can occur due to graphics card or driver issues, or if the scene contains incompatible materials or too many high-intensity lights.

To help us investigate:

1. Does this issue only occur in this specific file? Can you open your other D5 files normally?
2. Are there any imported files in the scene? If so, try hiding them to see if the glitch persists.
3. Try disabling FPS Booster.
4. Please send a screenshot of your D5 System Info and your hardware details from Task Manager.

This information will help us pinpoint the cause and suggest a solution. Thank you.
