There was a very strange problem. The fact is that when I look through some images in Android Studio, (including these are always white Material Design icons), instead of their transparent background - black. Everywhere, wherever possible: in the layout editor, just when viewed in the tab and even in the preview in Windows (!). And in the preview menu, so the picture does not appear at all.
At the same time, after the build, on the test device, everything is as it should.
Has anyone come across? The problem, though not critical, is very annoying.
