Workaround:
Could you use the new Client Launcher and create a desktop shortcut (or use one that you previously created from the new Client Launcher)
right click the shortcut and select properties.
append -Dsun.java2d.uiScale=1.0 to the “target” field.
Launch the designer or vision client.
Caused by windows scaling
