Indeed, I have downloaded, built and tested QScintilla and Scintilla directly, and everything works as expected with Scintilla (using their Cocoa ScintillaTest; I wanted to use the ‘qt’ version, but that folder doesn’t contain any test application) while it doesn’t with QScintilla (using your example-Qt4Qt5).<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>For my testing, I simply called:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US> $ defaults write -g AppleMagnifiedMode YES<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>then ran the QScintilla and Scintilla test applications, and then called:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US> $ defaults write -g AppleMagnifiedMode NO<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>and re-ran the QScintilla and Scintilla test applications, expecting a difference in the rendering of the applications’ various texts, including that of the editing widget itself.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Some screenshots illustrating the above can be found at </span><a href="https://github.com/opencor/opencor/issues/248#issuecomment-29712073">https://github.com/opencor/opencor/issues/248#issuecomment-29712073</a>. As you can see, there is no difference (i.e. blurry) in the way QScintilla renders its contents while Scintilla does, as expected, renders its contents differently depending on whether AppleMagnifiedMode is set to YES or NO.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Hopefully, this is an issue that you can identify and fix very quickly (I am really interested in some of QScintilla’s features, so it would be a real shame if I had to use Scintilla directly).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cheers, Alan.<span lang=EN-US><o:p></o:p></span></p></div></body></html>
