Please, wait a day. I'll try with virtual machines and real machines,
both.
And if you can bring some hardware information with a video card
driver, xorg-driver, etc,
it'll be helpful for finding the cause.

I guess too this is system specific. I'm on openSUSE Tumbleweed.
Changing editor's font to Droid Sans doesn't help.
Ok. I see that this issue is system specific, so my question is
answered. Maybe somebody can check this issue on Tumbleweed only?
Thank you.
