    4. Request: Proton-CachyOS Latest choiceOpen

      Its probably just more convenient to have a Proton-CachyOS Latest just like Proton-GE Latest instead of choosing a specific version everytime

    5. Add option to install Proton-GE as latest-onlyOpen

      The proton-ge package from AUR does the following patches: It makes both the internal and display name as Proton-GE only. This makes it so we only have to update the Proton version without always re-selecting a new global version and per-app versions when updating. Could you make…

    6. GE-Proton download doesn't filter architectureClosed

      Just a heads up -- GE-Proton now has -aarch64 builds, I got a bunch of misreports due to ProtonPlus and ProtonUp-Qt downloading the aarch64 version instead of the standard x86 version. aarch64 builds and shasums end in -aarch64.

    7. proton-cachyos and others Proton sourcesClosed

      No possibility to add a GitHub Proton source. 1) Add the proton-cachyos GitHub as another source to download and install their Proton versions. 2) Add the possibility to manually add a GitHub Proton repository. Thank You for your amazing work! Wish You well

    9. AppImage Version Unusable on Fedora Kinoite 44 as FUSE 2 Support Is DroppedClosed

      Fedora dropped FUSE 2 support with Fedora 44 release as it is unmaintained, and as a result I cannot use the appimage version of ProtonUp-Qt since updating to Fedora 44. My request is to use FUSE 3 instead, although I don't know how feasible that is for your project.

    11. Support use without a supported game launcherOpen

      As someone who doesn't use fancy game launchers and is working hard to excise all GTK stuff from my system before it upgrades to GTK4 (thus baking in blurry low-DPI fonts and tons of mobile-isms), I was hopeful about this but, after turning off all the Flatpak permissions for…

    12. Game List crashes with IndexError when a Heroic game's wineVersion name has no "-"Open

      Opening the Game List for Heroic (GOG games) crashes ProtonUp-Qt with an IndexError. updategamelistheroic() assumes wineVersion.name always contains a - (e.g. Proton - GE-Proton10-3) and takes the part after it. If the name has no dash, the call to split('-', 1)[1] raises and the…

    15. Game List: Sorting and refreshing results in broken entriesClosed

      Hi there, hitting sort (e.g. clicking on the compatibility tools, Game, Path or Runner-header) and then hitting the Refresh-Button afterwards will result in broken entries. Those entries could be duplicate game entries in the list, messed up paths that don't match their games…
