The Linux window draws again
On a machine with recent graphics drivers the launcher opened a white rectangle and stayed
there. Nothing was wrong with the launcher: WebKitGTK 2.42 and newer hand their rendering to
the driver over DMA-BUF, and drivers that no longer serve that path leave the page blank —
or, if you tried to work around it with software rendering, refuse the display outright with
Could not create default EGL display: EGL_BAD_PARAMETER.
The launcher now asks for the fallback renderer on Linux before the window is created. It is
the same UI at the same speed; nothing here was leaning on the GPU. Only when you have not set
WEBKIT_DISABLE_DMABUF_RENDERER yourself — an explicit setting in your environment still wins.
Windows and macOS are unchanged.
