I think you mean the latter. Whether or not the scale factor is involved, you can check by looking at what is selected in "Extras > Scale Factor" menu.<br>>> > <br>>> > I am not sure that I really understand what you mean.

One Pi has a 1920@180 screen and the initial window is notably smaller than what it was when I saved the image, the other has a 1920@1440 screen and the initial window size is what I set. That size is not larger than the 1920@1080 screen, by the way. To the best of my recollection this is new (mis)behaviour.<br>>> >> <br>>> >> We've always done some startup checks in the VM to fit the window within the available display limits but I don't remember previously over-riding the requested size this aggressively. Has anyone changed this code recently? Or is this a side effect of recent scale factor stuff? I can't spot any suspicious code in the image right now.<br>>> >> <br>>> >> tim<br>>> >> --<br>>> >> tim Rowledge; tim@rowledge.org; http://www.rowledge.org/tim<br>>> >> A misplaced modifier walks into a bar owned a man with a glass eye named Ralph<br>>> >> <br>>> >> <br>>> > <br>>> <br>>> <br>>> tim<br>>> --<br>>> tim Rowledge; tim@rowledge.org; http://www.rowledge.org/tim<br>>> Useful random insult:- Always responds to "Make Money Fast" postings on the Net.<br>>> <br>>> <br>>> <br>> <br><br><br>tim<br>--<br>tim Rowledge; tim@rowledge.org; http://www.rowledge.org/tim<br>Strange OpCodes: VMB: Verify, then Make Bad<br><br><br><br></tim@rowledge.org></marcel.taeumel@hpi.de></div></blockquote>
