159918 2016-07-19 06:02:29 -0700 [GTK][Threaded Compositor] Web Process crash when the page is closed before the web view is realized 2016-07-20 23:42:54 -0700 1 1 1 Unclassified WebKit WebKitGTK WebKit Local Build Unspecified Unspecified RESOLVED FIXED Gtk P2 Normal --- 154066 1 cgarcia webkit-unassigned berto bugs-noreply commit-queue gustavo mcatanzaro mrobinson oldest_to_newest 1212332 0 cgarcia 2016-07-19 06:02:29 -0700 When the web view is unrealized we send a sync message to the web process to destroy the native surface handle for compositing, and then we actually destroy the redirected window. But if the page is closed explicitly before the web view is unrealized, the drawing area proxy is destroyed so that when the web view is unrealized we can't notify the web process that keeps trying to render to a now deleted window handle. that produces a BasdDrawable X error and the web process crashes. The program 'WebKitWebProcess' received an X Window System error. This probably reflects a bug in the program. The error was 'BadDrawable (invalid Pixmap or Window parameter)'. (Details: serial 213 error_code 9 request_code 154 (DRI2) minor_code 3) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
