How it looks like currently

If LO is started on Windows with:

SAL_FORCEGL=1 instdir/program/soffice.bin

Then text in Writer is misplaced a bit. Given that the cursor caret still has the correct position, this is quite visible.

GL without glyph caching, good.

Typing "x" 10 times then selecting the last character should look like this.
