</div>
<p>Any thoughts on this? It seems like a definite JavaFX bug with hopefully a simple fix. Choosing any fractional scaled resolution may or may not cause the issue. I also wonder what other controls may suffer from the same issues.<o:p></o:p></p>

this issue. If it's 1.25, we see this rounding difference between the two numbers in this instance. If these two numbers are not equal, the calling code mistakenly assumes the overflow box is necessary.<o:p></o:p></span></p>
