Created attachment 117223 [details] screenshot with an underscore disappeared Sometimes some parts of symbols disappear. For example, an underscore may disappear completely. In the attached screenshot the underscore in type Term_Record is private; disappear, so that it reads "Term Record" instead of "Term_Record". The attached screenshot is a mild case of the bug. Sometimes all underscores on the screen disappear. Related bug of another program: https://bugs.kde.org/show_bug.cgi?id=371079
Created attachment 117309 [details] "Parser_Type_Without_Finalize" damaged Another screenshot where the bug looks even more noticeable. Some strings such as "Parser_Type_Without_Finalize" are damaged (underscores and other bottom parts of characters are not visible).
