No subpixel font smoothing in flathub version, subpixel smoothing in MS .deb version.

[trr]

Flathub version doesn't have subpixel font smoothing, while the .deb from Microsoft's repositories does, with same font and same config.

Using most recent flathub version at the time. I tried manually starting with --force-device-scale-factor=1 added to the flatpak run command as recommended by many sites and it didn't help.

This coupled with issues with certain extensions that don't expect to be sandboxed, and the in-built terminal needing extra tweaks makes the flatpak version a worse experience. No doubt there's extra difficulty passing in the font smoothing config into a flatpak app but other flatpak apps do manage as well as electron apps that don't use flatpak.

Various font-related flags I found in solving for blurry fonts on wayland (#471 (comment) ) ::

--font-render-hinting=none
--font-render-hinting=full

--enable-font-subpixel-positioning
--disable-font-subpixel-positioning

--enable-use-zoom-for-dsf

--force-device-scale-factor=1.12

--disable-gpu

And then this worked; which also already works in VScodium fwics:

flatpak --socket=wayland run com.visualstudio.code --enable-features=UseOzonePlatform --ozone-platform=wayland

edit: here's my .desktop file, which supersedes the system com.visualstudio.code.desktop:
