[BUG]s TLB Beta 7.3.4 Text Not scaling on High DPI Display

Separator lines are still too fat (I've attached a full-scale screenshot)
Notice in my full-scale screenshot that the separator lines are 6-pixels tall - My Dell XPS-15 notebook screen is scaled at 225%, so I would expect the lines to be (at most) 3 pixels tall

The default size of separators is 2 pixels. So:
2 * 225 / 100 = 4.5
In the next version the size will be 4 pixels for 225% scaling.
