I’ve got a user who is having issues with my app. Apparently they normally run it at 300% scale (a combination of high-DPI screen and readability of text sizes) and it looks like this:
There’s supposed to be text above that image, more text in several widgets beside and below “Lincoln’s Bible”, avatar images in the top-right of each item, and several icons in other
If they use the GTK inspector then widgets do get rendered as they click on them (GIF recording). After a bit more debugging, they’ve also found that everything works fine at 200% scaling, but that’s not large enough for their normal use. They’re apparently not getting any warnings from GTK on the console, so whatever it is then GTK doesn’t obviously think there’s a problem.
Does anyone know what might cause this? They’re not seeing the same issues with other apps, but it seems odd that it’s only 300% scaling that triggers it. I’m not aware of anything particularly strange that I’m doing (no custom rendering for the widgets on display here).
