Current Behavior

When running albert with QT_QPA_PLATFORM=xcb albert or albert --platform xcb the launcher is blurry/pixelated on my HiDPI screen, as I'm scaling the display output by 2x.

However, when launching albert with albert --platform wayland the launcher is not blurry but I'm facing the same issues described in #1321.

Expected Behavior

The launcher to be scaled at the correct DPI.

Setting QT_AUTO_SCREEN_SCALE_FACTOR and QT_SCALE_FACTOR also had not effect.

Anything else?
