--- Comment #8 from Mike Kaganski  ---
I don't know if the problem is actually caused by this, but we had a wrong code
causing those "warn:vcl.gdi:5420:5816:vcl/win/gdi/winlayout.cxx:86: Binding of
font failed. The font might not be supported by DirectWrite" warnings, that
prevented caching of glyphs, which really could impair performance.

Testing with daily and posting feedback is welcome.

Second example Writer (bisected it to the same commit)
1. Open attachment 137388 (with OpenGL enabled)
2. Enable formatting marks
3. Scroll down

The cygwin terminal is also flooding with this when scrolling around with
OpenGL enabled:
warn:vcl.gdi:5420:5816:vcl/win/gdi/winlayout.cxx:86: Binding of font failed.
The font might not be supported by DirectWrite.

I think not.  Bug 104716 is about:
(a) a Writer document (not Calc)
(b) with big/complex(PNG)images
(c) with or without OpenGL enabled
(d) the bug is older than this one (should be introduced around 2017-07-21, if
my bibisect is correct)

tdf#107166 improve AA mode selection, retry, more checks
Major problem when setting the render mode and the text antialias
mode is that when you set the render mode to something that isn't
compatible with the text antialias mode, then every next call will
cause an error (invalid parameters). So we need to be sure that we
never set incompatible modes. Additionally we just need to set it
one time when we create the surface and not every time we draw.

If we get the D2DERR_RECREATE_TARGET we can create a new render
target and retry the whole call. Somethimes this is not possible
so we try 3 times and the give up.

We need to add more checks where we exit early or not continue with
some calls as any additional calls could taint the draw state and
some things wouldn't be drawn. For example if we calculate the
sizes of 0 glyphs we shouldn't continue with binding the hDC with
an "empty" rectangle. This will fail and cause some text that is
called afterwards to not draw.
