Blank Spaces for about half of capital letters

but not for lower case. I did not have the problem yesterday, which was when I installed 5.2.0. Any help?

Put some effort into writing your question. Don’t leave us guessing.

I get blank spaces when I type about half of the capital letters, but this doesn’t happen for the lower case letters. Has anyone else had this problem, or have any idea what I can do about it?
