[Evolution] Bug#839222: evolution: Not white, but displays garbage pixels

[Christopher Sasarak]

Package: evolution
Version: 3.22.0-2
Followup-For: Bug #839222

Dear Maintainer,

Evolution doesn't crash, but in the preview message pane I get garbage.
Additionally, I get the same thing when I try to open the message in a
new window. Sometimes when I click to another message the garbage pixels
change. It's still garbage, but it looks like it's trying to display the
message. 

When I open the program in a terminal I get these error messages:
** (evolution:2883): WARNING **: Couldn't register with accessibility
bus: Did not receive a reply. Possible causes include: the remote
application did not send a reply, the message bus security policy
blocked the reply, the reply timeout expired, or the network connection
was broken.
OpenGL Warning: crPixelCopy3D:  simply crMemcpy'ing from srcPtr to
dstPtr

** (evolution-alarm-notify:2897): WARNING **: Couldn't register with
accessibility bus: Did not receive a reply. Possible causes include: the
remote application did not send a reply, the message bus security policy
blocked the reply, the reply timeout expired, or the network connection
was broken.

** (WebKitWebProcess:2936): WARNING **: Couldn't register with
accessibility bus: Did not receive a reply. Possible causes include: the
remote application did not send a reply, the message bus security policy
blocked the reply, the reply timeout expired, or the network connection
was broken.

(evolution:2883): Gdk-CRITICAL **: gdk_window_get_window_type: assertion
'GDK_IS_WINDOW (window)' failed

which leads me to suspect the problem is with libwebkitgtk2-4.0, but I'm
not sure. I also get similar bad behavior when I open a browser which
uses that webkit library like epiphany, but not  midori which depends on
an earlier version.

I tried going into the settings and setting Evolution to only ever show
messages at plaintext, but this didn't fix the problem either. 

Occasionally Evolution won't start and I get this error in addition to 
the others:
(evolution:3925): Gdk-ERROR **: The program 'evolution' 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 1463 error_code 9 request_code 143 (DAMAGE) minor_code 1)
(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.)
fish: “evolution” terminated by signal SIGTRAP (Trace or breakpoint trap)

But am not sure that it's related.
