Compositor 1.4.5-linux-alpha.3 for Linux — signed Flatpak alpha, x86_64.
Maintenance release on tip 1.4.5 Linux catch-up:
-
Editor behavior matches 1.4.5-linux-alpha.2 (live gradient preview, Copy Merged/Paste, Smudge/Liquify latency, multi-layer Cut, Unofficial port download page, Skia Ganesh Flatpak build).
-
Remove the Linux UI e2e suite and graphics E2E bench from the repository and CI; smoke and unit tests remain.
-
Install from the Linux download page or the attached
.flatpakreffile. The signed alpha repository supplies future updates. -
Use Compositor → Check for Updates… → Check and Update, your software center, or
flatpak update com.compositor.Client. -
Updates run without closing documents. Save your work and reopen Compositor after installation.
