series of 400% magnified clips of a Writer canvas table

So, confirming on Windows 10 Ent 64-bit en-US with nVidia GPU and
Version: 5.4.1.2 (x64)
Build ID: ea7cb86e6eeb2bf3a5af73a8fac570321527
CPU threads: 8; OS: Windows 6.19; UI render: GL; 
Locale: en-US (en_US); Calc: group

Attaching a PDF of a series of Windows screen Magnifier clips of a Writer table
with "11" entered in its cells on a 1920x1200 resolution monitor.

Clips start with Writer document canvas zoomed to 200%, and decrease down to a
90% zoom. At each zoom step the rendering of the canvas noticeably changes at
the right edge of the entry, but the "one rendered as a tic" issue clearly
shows at the 100% zoom. Below 90% the rendering to canvas is too small to have
any differences.

Default HA or CPU only rendering does not mangle the right most character and
both are shaped the same.

Demonstrates that the OpenGL rendering is not setting the same bounding box as
used for default rendering uses.

I can reproduce this issue in Windows 8.1
Using zoom level between 66 and 71 or using Arial with font size of 8 and zoom
to 100%.
To me seems like bug 111882.

Version: 6.0.0.0.alpha0+

(In reply to Willim from comment #9)
Looking at the msinfo32 Display panel you posted (thank you BTW), with current
Intel driver (15.40.34.4624/20.19.15.4624) the Intel HD Graphics 4400 iGPU of
your Haswell (2013) i3-4160 CPU should be well supported on Windows 10. You
might update to the latest Intel driver (15.40.36.4703)[1], but would not
expect that to fix this isolated OpenGL DirctWrite rendering issue.

No, OpenGL rendering and default HA or CPU rendering all "read" the font
metrics for each font, and "stamp" glyphs using those metrics. Believe it is
the stamping of the glyphs to canvas that differ between OpenGL and default
rendering.

Myself I have not see this "clipping" of a specific font, usually the whole GUI
would be affected dependent on OpenGL driver support for particular GPU. I can
not reproduce this effect on Arial font with Intel HD Graphics 620 GPU with
same Intel OpenGL driver.

You might use an external utility (BablePad, or MainType, etc.) just to verify
your version of the Arial font is the Windows 10 correct MonoType v6.90 (Arial
regular, 2015, w/3127 characters).

As it does toggle correct when disabling OpenGL setting to new. Though it would
be helpful if we had a few others reproducing.

@Tomaž, Khaled, Tor--thoughts on OpenGL mishandling a font metric then clearing
up with default rendering? Anything specific the OP could provide that would
help diagnose?
