compressed screen fonts

Since upgrading to OS X 10.11.1, I’ve noticed a strange problem in DTPro’s display. Where text in columns used to be truncated if the column was too narrow, it’s now compressed to the point where it’s almost unreadable. (I’ve attached a sample screen grab.) There was a similar problem with MailTags, but it’s since been corrected. No other app seems affected. Would appreciate thoughts on how to correct this, if possible. Thanks.
