1532024 - [Wayland] Wayland sometimes displays an empty window with WebRender with GDK_BACKEND=wayland

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, enhancement)

Description

[Sotaro Ikeda [:sotaro]]

There is a case that main window becomes empty window with "GDK_BACKEND=wayland ./mach run". It happened often when PC was very busy.

When it happened, GetRemoteRenderer() returned nullptr in nsWindow::WaylandEGLSurfaceForceRedraw().

In this case, it seems better to call RequestsUpdatingEGLSurface() in nsWindow::OnExposeEvent() like before.

In this case, it seems better to call RequestsUpdatingEGLSurface() in nsWindow::OnExposeEvent() like before.

nsWindow::SetCompositorWidgetDelegate() seems more reliable than nsWindow::OnExposeEvent().
