what are the feature?

There should be visual cues, otherwise users will think the system is broken.

Normally there are visual clues indeed. I don't know why there are none in helloSystem; possibly we are missing something in the KWin bundle?

Have you fixed it recently? Because it works fine on one of my graphics cards NVIDIA GeForce GT 440, but the others don't.

Then on that graphics card it feels like the driver is not used, because the window has no shadows, and the browser does not execute.

And I also like the shape of its prompt box.

Something is deeply broken with that graphics card. Which card is it?

[louies0623]

NVIDIA GeForce GT 440

Moved the GPU issue to its own ticket, helloSystem/ISO#524, it is a separate issue.

I was able to fix (and disable) the active corner animation, but we are still missing (again) the window snap animation. I don't know yet what needs to be done to fix it (again).

What’s confusing is that this will only display normally when the graphics card is faulty. My guess is that the theme may have overwritten it.

@probonopd I have an idea, just a speculation, that the visual prompt is successfully displayed because the graphics card is driven by X11, not nvidia, so the BreezeEnhanced effect is not turned on, and it displays normally.
The bug is BreezeEnhanced not the kwin.
