i already rendered several scenes in blender and this is my first time to encounter this. After the compositing, the rendered image looks weird, some kind of distortion or something. I can't find any answer on google. Is it a bug or something? I use blender 2.83. Note: the model is a very simple mesh.

    $\begingroup$ Hi and welcome. The problem may be because of denoising at a low sample count. To solve it, you can try increasing the sample count to reduce noise. $\endgroup$

I've read some comments above and try their suggestion, and the problem is that i have a very low sample count. The solution is of course to increase the sample count. Thanks to them.
