Bug 281279 – GTK3: invisible HTML rendering, "AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer"

• Component: WebKitGTK
• Status: NEW

[Thomas Zajic]

Hi,

This is a follow-up/spin-off report to bug #261874 and bug #263645, as suggested by @Michael Catanzaro.

Since (at least) webkitgtk-2.42, GTK3 apps (ie. apps using the 4.0/4.1 API/ABI) only show an empty (for example "liferea", a GTK3 RSS feed reader) or black (for example "yelp", GNOME's integrated help system) area where the HTML rendering output is supposed to be, unless either WEBKIT_DISABLE_DMABUF_RENDERER=1 or WEBKIT_DISABLE_COMPOSITING_MODE=1 is set. On the console, the error message "AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer" is repeated several times.

Note that the HTML rendering is not *missing*, but only *invisible*. If you know where the elements are supposed to be and hover over them with the mouse, the mouse cursor changes accordingly (ie. from "arrow" to "pointing finger" when hovering over the place where a link should be visible).


My setup:

* Slackware64-15.0
* GNOME-47.0, running a ...
* gnome-flashback-3.54.0 session using ...
* metacity-3.54.0 in an *uncomposited* X11 environment ("gsettings get org.gnome.metacity compositor" => 'none')
* gtk+-3.24.43
* webkitgtk-2.46.1
* GPU: NVIDIA GeForce GTX 1660 Ti
* GPU driver: NVIDIA-Linux-x86_64-550.120 (ie. the binary, proprietary one)
* GPU driver settings:
