Photo of window borders

SUMMARY
I have had not problems prior to installing the NVidia driver. Now, many themes have a broken window border as seen on the picture. Frankly, the problem doesn't occur with Breeze. So you could simply say the other themes are broken or outdated, but since it only happens on NVidia, I think there is another problem.

STEPS TO REPRODUCE
1. Install official NVidia driver
2. Install a transparent theme like Harmony or Orchis-Dark
3. Try to remove window borders with setting options to "No borders" in window decorations

OBSERVED RESULT
Window borders are bigger than ususal and can't be removed.

EXPECTED RESULT
Window borders should behave normally and be removable.
