Error when using background blur

(I’m not sure whether this is the right section)
So I’m using background blur on UMG for blurring on my pause menu. Everything worked out fine when I tested it however, I receive this error message in the editor log:

LogRHI: Error: GetAndOrCreateGraphicsPipelineState RenderTarget check failed with: 512

And the error only appeared whenever I used background blur (when I detached the nodes for setting the blur strength the error disappeared). I’ve tried this using the blur on other widgets within the same project and the error still pop up. However, I cannot reproduce this error in a clean project. Does anyone know where I did wrong?

I have same problem… my engine version is 4.18.1

I’m also getting this in 4.19 now after converting from 4.18

If you have Background blur in your widgets in 4.18 and open the project in 4.19. I get this error, doesn’t seem to break anything, just gives the error:

LogRHI: Error: GetAndOrCreateGraphicsPipelineState RenderTarget check failed with: 928 !

Changing blur strength in the widget to 0 gets rid of the error…and the blur. Not really sure why or what the problem is. Even with the error the blur functions fine. The error isn’t much detail to go off of so I dont know where to really look for the cause ​​​​​​. What does the “928” reference? Donno if its a bug or something with my project settings, but wasn’t giving the error in 4.18

LogRHI: Error: GetAndOrCreateGraphicsPipelineState RenderTarget check failed with: 1928 !
even to me 4.18.3

Has anyone solved it? I have the same thing: LogRHI: Error: GetAndOrCreateGraphicsPipelineState RenderTarget check failed with: 928 !

I think the only way to solve this is either up/down grade your version of UE4. I was using 4.19 preview 5 and when I updated to 4.19.0 the error disappeared.
