Additional information
Change cura theme or QT scaling variable doesn't solve the issue.

[nallath]

I don't have the issue myself, so I'm not sure if my changes actually solve it.

[smartavionics]

That change made no difference for me although what I see isn't as bad as the example above.

[Mosher23]

same on Mac OS X Settings window is also not resisable

[njibhu]

I don't have the issue myself, so I'm not sure if my changes actually solve it.

Will try the patch this afternoon and will get back to you

same on Mac OS X Settings window is also not resisable

I actually can resize the window to make the G-Code input wider, I do not think that the bug is related. Though changing the window size for me doesn't change anything on my bug

[njibhu]

@nallath tested by rebuilding an appImage, the problem is still here..

[njibhu]

@nallath Found a fix and a way to reproduce it.
Using as a system font Noto Sans 10px, the bug is there. If i switch to Liberation Sans 11pt, it's gone. (with Liberation 10px, the input is still offset, but at least readable).
So it's definitely linked to font size
I switched to Droid Sans 10px, and the bug is gone.

[Ghostkeeper]

Not reproducing the problem with that on Ubuntu when running from source, but it is affected by it. This is my machine settings dialogue for Ender 3 using Noto Sans 10px:

And here is the dialogue using Liberation Sans 11pt:

But when you're using the AppImage, it should always use Noto Sans 10pt, so I wouldn't expect this to have any differences between systems on the builds.

[Pimentoso]

+1 for the problem on MacOS, please make this dialog resizable. Catalina 10.15.4, cura 4.5

[nallath]

The dialog has been made resizable already.

[Mosher23]

The dialog has been made resizable already.

But not on Mac OS or not in 4.5

[Pimentoso]

The dialog has been made resizable already.

Doesn't look like it. Also tried to resize it using a window manager (Rectangle) but it still doesn't change.

[nallath]

It wasn't done in 4.5 if I remember correctly (soo that means it will be in 4.6)

[Ghostkeeper]

The window is resizable in Cura 4.5 in Linux. If we made a change in 4.6 it must've been to fix something in MacOS only.

I also remember this coming back up recently, but I can't find the commits or any change that we made to fix it, and don't remember that we made any special handling for MacOS then.

[jlsjonas]

@rburema might know more? @Ghostkeeper

[Ghostkeeper]

This should be fixed in Cura 4.7, through this PR: https://github.com/Ultimaker/Cura/pull/7883
