Details

(Whiteboard: tpi:+) 

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.152 Safari/537.36 OPR/29.0.1795.60

Steps to reproduce:

Drag a web page element or selected text from a page running in X11


Actual results:

Firefox creates a shaped X11 window regardless of compositor existence, leading to extremely slow rendering when the desktop is composited.


Expected results:

Firefox should check for compositor existence on startup (check _NET_WM_CM_S%d atom per "screen") and use argb windows for composited environments.

This is a known issue with early versions of GTK3, but what version is installed on your system?
Ah, I hadn't retested in some time. This appears to be resolved now and drags use argb windows as expected.
