Buttons in search toolbar move under cursor

[loefflerd]

In TeXStudio on a Mac, when using the Find / Replace commands, the "find next" / "find previous" buttons in the toolbar move from side to side as they're used (possibly because of the way mac OS automatically shows / hides the scrollbar?). This is highly inconvenient when clicking through a document to find a particular occurrence of a search term. Here's a brief screen recording showing what I mean:

screen recording (3 sec)

Environment

• TeXstudio: 4.5.1
• Qt: 6.4.2
• OS: Mac OS Ventura 13.2.1 (22D68)
• TeX distribution: [using TeXLive 2019, but I don't imagine that's relevant]

Expected behavior

Buttons remain where they are when you click on them!

Actual behavior

Buttons move left briefly when clicked, then move back a second or so later (wiggle is enough that sometimes you accidentally click "Find Previous" when you wanted "Find Next" which is very annoying)

How to reproduce

Use "Find" in any document long enough not to fit in the window all at once

happens when osx is set to show scrollbar on scroll only.
