Flickering in Unreal Editor on Linux

Development Getting Started & Setup

Hi,
I’m just getting things set up and have loaded up the Stack O Bot project in the editor. I’m experiencing a lot of flickering.
flickering

Has anyone else experienced it, and/or does anyone know how to get rid of it? I’ve tried hiding various things, mostly the environmental/atmospheric items. When running the game, flickering only occurs above the ‘horizon’.

I’m on Linux Mint, using Nvidia drivers 515. (I’ve also used 470, and the flickering was the same there. Edit: I will amend this and say that the flickering was worse on 470.). I’m using UE5

Thanks!

Not solved, but I’ve been able to reduce the flickering significantly by turning off
Show → Lighting Components → Global Illumination
Show → Lighting Components → Dynamic Shadows

Now the flickering is mostly contained to the upper left quadrant of the viewport.
