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.

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.

That's because holding down the Alt or Option key while using Filter>Render>Clouds or Difference Clouds produces higher contrast clouds.
That's by design.
If you render clouds on a document whose size is a multiple of 128, you get tileable results.

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.
