WebKitGTK aborts the whole process with "Could not create default EGL display: EGL_BAD_PARAMETER. Aborting..." on systems without a working EGL/GPU context (VMs, older Mesa, no GPU passthrough) — visible as a terminal abort on Ubuntu 26.04 (#135) and as a silent "won't open" when launched from a .deb-installed GUI launcher on Linux Mint 22 (#139). Set WEBKIT_DISABLE_COMPOSITING_MODE and WEBKIT_DISABLE_DMABUF_RENDERER before the Tauri builder starts (Linux only) so WebKitGTK falls back to software rendering instead of aborting. disabled

Summary
Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...on systems without a working hardware EGL/GPU context (VMs, older Mesa, missing GPU passthrough) — reported as a terminal-visible abort on Ubuntu 26.04 (GitWand starts and displays a blank window only! #135) and as a silent "app won't open" after a.debinstall on Linux Mint 22 (Cannot open the App | deb | Linux Mint 22 x86_64 #139).WEBKIT_DISABLE_COMPOSITING_MODE=1andWEBKIT_DISABLE_DMABUF_RENDERER=1on Linux, before the webview is created, so the app falls back to software rendering instead of aborting.#[cfg(target_os = "linux")]).Test plan
