bug#50660: 28.0.50; Text artifacting when the cursor moves over text under mouse face that originally displayed a box

[Po Lu]

Thanks for the clarifications.  One last question though, if I make the
change to setting the face in draw_glyphs, it would be OK to remove
x_set_mouse_face_gc, because the face is already set correctly by
draw_glyphs, and no other adjustments to the GC or glyph string will be
required, right?

Thanks.
