Hi all,

since upgrading webkit2gtk from 2.40 to 2.42 we have several rendering problems in our environment. They reach from grey artifacts (mostyly when dragging) to complete white/gray rendered webpages. We assume this might be because of our quite special environment where we use XFCE without compositing on GTK3. We tracked the bug done to occur since the new DMABUF implementation in d2424c0fc67f6a46921edb52874720bb99c0c699. Should this be working on non compositing X11 window managers? we applied a patch to disable DMABUF rendering if the window manager does not support composition. Please let us now if a patch is wanted and if it should work how we can help in debugging the problem.

Regards,
Jan
