Bad scaling on icons and text

[dblsaiko]

Description

The font in the chat UI is rendered (supposedly) at 1x scale and pixelated. All icons are also pixelated.

Steps to reproduce

• Use KDE on a 4k monitor with global scale set to 1.5x

Version information

• Quaternion version: 0.0.9.4b
• Qt version: 5.13.2
• Install method: AUR
• Platform: Arch Linux x64, Plasma Desktop

Setting UI/Fonts/render_type to QtRendering seems to fix the font issue. Icons are still pixelated though.

Sorry - this got lost in the traffic and I just found it. Is that on X or Wayland? X is known to be bad at handling fractional scale factors. Also, high DPI scaling on Qt only got reasonable support for fractional scale factors since Qt 5.14. If you're still around, can you try it with Qt 5.14 or later?

That was on X (and I'm still on X). With Qt 5.15.2, the text looks fine although icons (like the close/detach icons on the panels in the screenshot above, or menu icons) are still pixelated. That should be able to be fixed like here though, I think.

Aha, thanks, I didn't know about that attribute.

Turned out things are a bit worse: avatar dimensions in a few places were hardcoded to 16px :-\
