jitter problem for example "basic_sample_super_resolution_dx12" with static draw

I am trying to integrate Intel XeSS into my project, but I found that it causes jittering/flickering when rendering a static scene. I tried to compare the code differences between my implementation and the sample project "basic_sample_super_resolution_dx12". After disabling the triangle movement code, I was able to reproduce the same issue. Attached are screenshots of the visual artifacts and my code modification diff
