Arch Linux User Repository

If anyone, like me, uses this on GNOME on Wayland with Fractional Scaling (due to a 14" 2560x1440 screen in their laptop), you may find this Electron trick useful to make the app work in native Wayland mode instead of xwayland (so that it does not appear blurry) - run the app with this command:

losslesscut --ozone-platform-hint=auto --enable-features=WaylandWindowDecorations

To make the change persist, change the Exec=... line in /usr/share/applications/losslesscut-bin.desktop to:

Exec=losslesscut --ozone-platform-hint=auto --enable-features=WaylandWindowDecorations

It would be probably great if the .desktop file in this AUR would have this automatically included if Wayland is detected as the display server, but I'm not sure how do you go about this; Also this seems to be a recurring theme with all Electron apps, so I'm thinking about some system-wide solution to be brought up on Arch upstream - no point in having every single Electron app packager waste the effort repeating this.

I'm following the releases on this page: https://github.com/mifi/lossless-cut/releases

I'm not following all the tagged versions.

@tee fixed.

Makes sense, but it'd be nice if maintainers were given even the most modest of warnings that a breaking change was being rolled out.

@dontdieych thank-you for the patch - applied and the build worked locally.

@danielwerg thank-you - icon should be working now.

Add aarch64 support. All my email accounts need to register 2-factor auth for git send-email (don't like it :D). So ... paste here output of git format-patch.

I don't think you have to put icon file extension for Icon field in .desktop, some applications launcher won't render it as well.

- Icon=losslesscut.svg
+ Icon=losslesscut

@Lulzagna thanks for addressing my issue so quickly

@eniac should be fixed now.

Sorry about that - I slapped the repo's .desktop file in without giving it a good look. I merged the old and new so the MimeType is set as well.

The .desktop doesn't appear in gnome on my pc, maybe because it references /app/bin/run.sh which doesn't exist

seems like not following ~/.config/electron-flags.conf ?
