Bug 426302

Thanks for making the report!

I cannot reproduce this problem in krita/4.3 branch. Neither on Linux nor on Windows.

And I cannot reproduce that in release package of 4.3.0 either :(

version tested

Tested in this version, I was able to reproduce it.
The window created as "new view" does not behave as expected.
I hope that when I insert my cursor in the floating window created with "new view" I can zoom in that window using the mouse wheel.
But that doesn't happen or it happens badly, confusing. The main canvas is scrolling abnormally, zooming is not properly done, and strange things happen.
Watch the video, I'm just trying to zoom in on the floating window but everything scrolls and gets altered and everything needs to be relocated.

I use 2 monitors but Krita only occupies 1

I cannot reproduce it either (on Linux Mint + Cinnamon, using an appimage). Does it still happen to you @romopua in latest version (4.4.2-beta2)? If so, can you please share Help -> Show system information for bug reports?

Gif with the problem

Notice here how I zoom in on the small window, the large window scrolls up and down.

I'm not sure, this is useless to have a thumbnail preview window because a floating window overlaps another floating window.
That is, if you have a maximized window, the smaller window will be behind the larger window, so this prevents having a smaller window showing a preview because it will be covered by the maximized window.
Krita simply has no option to display a floating preview window.
To achieve this, you must dock the window to a tool area, there the window will always remain visible.

In the future you may also do this yourself when providing needed information.

I cannot reproduce this either... That makes three :(
