Hi Tony --<div><br></div><div>I added some checks via Graphics-mt.517.

While this is usually fine, failing primitives could make things more challenging. Especially since ui-scale changes might try to also resize the host-window now, which you observed via:</div><div><br></div><div><span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px">Preferences setDemoFonts.</span><br></div><div><span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px"><br></span></div><div><span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px">... which is just a deprecated interface for ...</span></div><div><span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px"><br></span></div><div><span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px">Display uiScaleFactor: 1.5.</span></div><div><br></div><div>Not sure what you mean by "<span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px">host </span><span style="font-family: Arial, Helvetica, sans-serif;font-size: 13px">window size jumps around all over the place". The only thing that might happen is that the primitive is called twice if the first call did not quite yield the expected size due to host-window decorations. In that case, the delta is added and tried again. But no more re-try after that.</span></div><div><br></div><div>Best,</div><div>Marcel</div><div class="mb_sig"></div>
