JFXTabPane cosmetic drawing bug with Windows scaling

[LightSnowDev]

The JFXTabPane does render incorrectly with scaling in Windows 10.
The line underneath the individual tabs is bigger than the tab itself.

125% and 150% scaling:

With 100% scaling everything is as expected:

This does not break any features or similar. It's just a cosmetic thing.

My setup:
Windows 10 1803
Oracle Java 10.0.1
JFoenix 9.0.4

@LightSnowDev thanks for pointing out the issue 👍

@LightSnowDev unfortounetly I wasn't able to reproduce the issue, I tried to change the scale to 125% , 150% however no luck in reproducing the issue.

@jfoenixadmin I created the most simple project i could think of with IntelliJ IDEA.
Just a fxml is being loaded. A controller is not used.
Source code and the final jar as zip:

sample.zip
generated jar.zip

I can confirm the bug.
JavaFX 11.0.2
JFoenix 9.0.9
Windows 10 Pro
Windows Scale: 125%
Resolution: 2560 x 1440

It looks like, that the line is 125% long.

If you don't mind losing the animation of the line from the previous selected tab to the newly selected one, I got a work around for you!!! Hide the selected tab's line and add a border at the bottom. The CSS snippet below does just that.
The CSS file containing this code should be added to the tabPane stylesheets.

//Hide default line of selected tab
.jfx-tab-pane:top .depth-container .tab-header-area .headers-region .tab-selected-line {
    -fx-background-color: transparent;
}

//Add border at the bottom of the selected tab
.jfx-tab-pane .tab:selected 
{
    -fx-border-width : 0 0 3 0;
//IInsert the color of the selected tab's line you wish to have
    -fx-border-color:  #d0d0d0;
}

A simple work around for this is,

.jfx-tab-pane .tab-selected-line { -fx-background-color: -fx-light-accent-color; -fx-scale-x: 75%; }

I don't know if @sshahine will ever update this, but I think I was able to solve this on my own copy at this line by wrapping selectedTabLine.prefWidth(-1); with a call to snapSizeX.
