Just perform a search on the Qt bug reporting system, and if you don’t find one then report a new one. If they can reproduce it, they’ll assign a level of importance (probably not super high) and that will be all you can do in light of fixing the problem yourself - or more likely - finding a workaround for your particular application.</div><div class=""><br class=""></div><div class="">-Patrick<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Apr 26, 2020, at 11:16 AM, Raymond Osborn <<a href="mailto:rayosborn@mac.com" class="">rayosborn@mac.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html; charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">I do nearly all my testing in conda environments, and as far as I can tell, the PyQt and Qt dependencies seem to require the versions to be nearly the same. I also don’t know if this is dependent on the MacOS version. The problems seem to coincide with the release of MacOS 10.13 (High Sierra) in 2017, so it might just be that the Qt developers didn’t keep up with some change in the Mac APIs after v5.10. However, the problems have now persisted for over two years through four PyQt versions, so I hope they are aware that this is still an issue.<div class=""><br class=""></div><div class="">Ray <br class=""><div class=""><br class=""><blockquote type="cite" class=""><div class="">On Apr 26, 2020, at 12:13 PM, Patrick Stinson <<a href="mailto:patrickkidd@gmail.com" class="">patrickkidd@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html; charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class=""><div class="">I recall posting or commenting on a Qt bug report about vertical alignment or something similar, but I can’t remember what it was.</div><div class=""><br class=""></div><div class="">Are you saying that this behavior occurs when changing to PyQt5-5.11 but using the same Qt version?

Everything seems to be fine on Linux, at least with 5.12. <div class=""><br class=""></div><div class="">I am writing to ask if anyone has also experienced an issue with the alignment of pixmaps in QPushButtons.
