Writer ODT file showing the font artifacts.

I must stress that the behavior that I'm seeing in Writer on various typefaces absolutely does NOT occur in MS Word 2016. It is NOT the font face. Fonts that render perfectly in MS Word 2016 render with small artifacts on the page in Writer. 
The size of the font and the magnification of the document does not matter. The artifacts (little squiggles beneath certain letters, like the letter "s") appear at all sizes and magnifications.

I have noticed since this the beginning of 5.x
I have attached a sample Writer .odt file with Lucida Handwriting embedded in the document. It makes for  a 4MB file and takes about 20 seconds to open (which isn't what I'm writing the bug about).

Unable to locate artifacts.

Is it affected by Tools - Options - LibO - View - Use OpenGL for all rendering?
Please attach a screenshot.

Set to NEEDINFO.
Change back to UNCONFIRMED after you have provided the information.

It is indeed caused by 
Tools - Options - LibO - View - Use OpenGL for all rendering

Clearing this option and restarting caused no problems.
I'll try to attach the screen shot with the OpenGL rendering on.

In addition to the small ticks below each lower case s, notice that the first f in fancy has a tick in the stem, only showing up when typing the letter a after it. the second f in font doesn't have that problem.

Ok, I think we can close this as dupe.
