Black bars that go away when window is moved - how to prevent bars or redraw window?

Version info

v4.6.stable.mono.arch_linux
Compatibility renderer
Low processor mode
Project Settings > General > Display > Window > Scale Mode: fractional, but also occurs on integer
Happens on debug and release builds
I resize the 2nd scene in code:
var size = DisplayServer.ScreenGetSize(); DisplayServer.WindowSetSize(new Vector2I( Convert.ToInt32(size.X * 0.60), Convert.ToInt32(size.Y * 0.12 * ProgressBarManager.Count) ));

Question

imageHere’s the first scene:

Here’s my scene transition:

image942×162 15.6 KB

Here’s how it looks like on screen:

Here’s how it looks when I grab the window and move it even one pixel. This is exactly what I want the window to look like:

What I’ve Tried

  • Changing the scale mode from fractional to integer
  • Using code to moving the window one pixel to the left after _ready()
  • RenderingServer.ForceDraw()

I am pretty sure from other black bar questions that I’ve read that I am causing this by resizing the window in code, and the black bars are appearing as the window/UI is trying to scale in response. What can I do to either prevent the black bars from showing up or force a window redraw in code to make them instantly go away?

First of all, check the problem on another system.

Thanks tomcat! I’ll ask some friends to try in the next few days and let you know what I find. I appreciate your suggestion.

@tomcat You were correct! Some friends tried my app on Windows yesterday and did not have the issue. This is a Linux display issue.
