Additional Context: This issue only occurs on Linux when running UI tests with the starter and driver framework.
The issue can be resolved by adding the following properties to Starter.newContext:

addSystemProperty("ide.ui.scale", "1.0")
addSystemProperty("hidpi", "false")
addSystemProperty("ide.ui.scale.override", "1.0")
addSystemProperty("sun.java2d.uiScale", "1.0")
addSystemProperty("awt.useSystemAAFontSettings", "off")

After adding these properties, the tests run successfully on Linux environments.
