Right icons are tiny on High DPI screens #226

Closed NatoBoram closed 7 months ago

NatoBoram commented 1 year ago

I have a screen that's slightly bigger than 1080p, but the right icons seem to have a strict pixel count to them, so they appear tiny

2304p

Since they're smaller than characters, they're really hard to see

Afaik, it is common for application to be DPI unaware, and usually the desktop environment can provide a sensible scaling. I don't have a 4K monitor, so I'm not really able to optimize for or test with high DPI displays. The dark style sheet, that this project uses, seems to have taken a similar stance on the matter. If Pop!_OS/Gnome doesn't automatically provide a sensible scaling, you could try to set the Qt scale factor environment variable:

QT_SCALE_FACTOR=2 ./cubiomes-viewer

QT_SCALE_FACTOR=2 ./cubiomes-viewer

With this, it seems like the scaling is somehow added to the one I already have, making the UI absolutely gigantic. The icons are still very small, but better

I have tried to avoid setting a fixed pixel size for icons in the newest 3.3. release, but I am not too hopeful that it'll change much. The checkboxes also appear very small and those are managed by Qt... You could try to additionally set the QT_AUTO_SCREEN_SCALE_FACTOR=0 environment variable to disable automatic scaling behavior and QT_FONT_DPI=96 to reset the font scale, or play around with a combination of these.

Version 3.4 now manages icon and text sizes more explicitly and allows you to specify a custom icon scale as well as fonts and font sizes. This should hopefully give enough options to make the tool usable on most displays.

Some built-in GUI icons, such as check boxes may, or may not, resize properly. This is a problem with Qt that I've tried to work around, but the results are still somewhat inconsistent.
