Hi everyone, I’m encountering a problem while drawing on a RenderTarget at runtime in Unreal Engine. Specifically, I’m seeing some strange line glitches that propagate across the RenderTarget, as shown in the attached image. Here’s what I’m doing: - **Setup** : I created a RenderTarget and a corresponding Material to display the RenderTarget on a mesh. - **Drawing** : At runtime, I am using Blueprints to draw on the RenderTarget. The drawing logic is supposed to continuously update the RenderTarget based on certain inputs. - **Problem** : While drawing, these unwanted lines and artifacts appear and propagate across the RenderTarget, creating a glitchy effect that ruins the visual output. Unreal 5.4 ![Screenshot 2024-05-22 162856](https://d3kjluh73b9h9o.cloudfront.net/original/4X/9/b/a/9ba3bea3ce13f8f3e4779cdb9024c37a7d6a890d.jpeg) ---

I am also trying to deal with a similar problem. I find posts about similar problems more than 5 years ago. I have not found a solution yet.
