Corruption in LibreOffice Writer

I have a Radeon 3000 graphics card and am using the X.Org radeon driver with the default settings (which, according to the man page, use glamor for the AccelMethod).  LibreOffice Writer 5.2.0.4 is practically unusable because of graphics corruption that occurs when scrolling or repainting the window.

Specifically, after scrolling the window vertically, parts of the document get painted over by copies of other parts of the window.  The overpainting also sometimes occurs when adding or removing text from the document.  Selecting parts of the document that exhibit the corruption don't restore the text; the corruption just gets highlighted along with everything else.

The problem does not occur when I tell LibreOffice to use gtk3 (via SAL_USE_VCLPLUGIN), but it does occur with every other toolkit (kde, kde4, gtk2, gen).

I tried manually changing the AccelMethod to EXA, but this causes a lot of flickering in my entire desktop environment (not just LibreOffice), particularly when dragging windows.  (Maybe my card doesn't support EXA?)

I am filing this bug for this product and component as the symptoms seem the same as in Bug 63397.  That bug was marked as fixed in the 1.18.4 release notes at <https://lists.x.org/archives/xorg-announce/2016-July/002699.html>, but as far as I can tell that's the version I'm using.

FWIW, the radeon driver still defaults to EXA for your GPU.

Please attach the corresponding Xorg log file.

I upgraded to xorg-x11-server-7.6_1.18.4-465.5.x86_64 and libreoffice-5.2.1.2-447.1.x86_64 and now can no longer reproduce the problem.  If you still want the log file, let me know, but I suppose it's no longer necessary.
