[Bug]: Buttons are too tall

[getArtemUsername]

Describe the bug

This is how it looks. The height of buttons doesn't match well with other elements. I switched from Win to Linux and now they look different, much taller. I assume this is related to high dpi displays and the scaling factor and it seems that the IDE scaling factor doesn't affect buttons. The default IDE themes have no issues with buttons.

The only option that the buttons react to is -Dide.ui.scale. Without it, the buttons are even much taller than in the screenshot.

To Reproduce

1. launch IDE
2. check buttons' height

Expected behavior

Buttons have reduced height or settings for height adjustment

Material Theme Version

v10.4.1

IDE

IntelliJ IDEA

Hi, did you change the zoom level in the Settings > Appearance to be bigger?

[mallowigi]

There was this issue that I didn't want to tackle: #381

Since this is a known issue, I think I'll do the opposite and remove all instances of using JBUIScale.
