Summary AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

Reported 2025-04-09 14:09:23 PDT
Created attachment 474879 [details] Minimal Sample I'm running in a bit of an issue with large webviews: I want to combine a webview with a gtk widgets based header seamlessly as a single "page". This works okay by putting the widgets + the webview into a scrolled window and then making the webview request the height of the loaded html content. This obviously bypasses webkitgtks internal scrolling. Now when the webview passes a certain height threshold the application simply freezes with ``` AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer (news-flash:993614): Gsk-CRITICAL **: 00:16:36.760: gsk_gl_driver_begin_frame: assertion 'self->in_frame == FALSE' failed ``` The Gsk-CRITICAL is printed over and over again until the application freezes and gets killed. I attached a minimal sample that triggers "AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer". However the application doesn't freeze and no Gsk-CRITICALs are emitted. A workaround for now is to disable the dma-buf code path with "WEBKIT_DISABLE_DMABUF_RENDERER=1"

Can you please attach a stack trace taken with G_DEBUG=fatal-criticals?

I just noticed that the minimal sample defaults to x11 for me. With GDK_BACKEND=wayland I hit the Gsk-CRITICAL with the minimal sample as well. The default Gsk Renderer for me is Vulkan. But I observed no change with GSK_RENDERER=gl or cairo. Everything is ran inside a fedora workstation 41 toolbox on fedora silverblue 41.
