Render>Clouds Strange Behavior When Using "alt+ctrl+f" Shortcut

I encountered a little strange behavior with Render>Clouds. At one point, I needed to create a terrain with perlin blur for my graduation project, and since I have been using Photoshop for years, it occurred to me that perlin blur works similar to render>clouds and I decided to use clouds. However, at this time, I noticed something strange. Whenever I pressed Filter>last filter (clouds) with the mouse, the whites in the output became more intense. However, if I pressed alt+ctrl+f, outputs with more prominent blacks were produced. This situation seemed a little strange to me. And you can easily see from the video below that it is not a coincidence.

That's by design.

But if Alt+Ctrl+F is the shortcut for Last Filter, which, since they made Ctrl+F Find, has always been with th last parameters used, which, in this case, was regular Clouds. Photoshop is reading the Alt key twice?

One of those shortcuts should be different.

That's by design.

If you render clouds on a document whose size is a multiple of 128, you get tileable results.

Same here. You can see the difference in the histograms. Left, invoked via the menu, right, via Alt+Ctrl+F:

These are both run on blank, 2048 pixel square docs.
