Most of the time, fbreader draws hyphens after each word in any book including its built-in help page. IIRC this started after switching to GTK. I cannot find any useful patterns in reproducibility, or guess why does it happen (I also tried looking at lsof and the config dir and check and change the app settings). I can reproduce it on two testing/sid systems, including one with an empty config.
I have version 0.12.10dfsg2-5 installed, and suffered the same issue. Found a fix for it. Go to Options, and select the Styles tab. Under "Options for", choose "Regular Paragraph". Click on the "Allow Hyphenations" checkbox until it looks grey or solid. Restart fbreader. Text in ebook is now no longer filled with hyphens. Cheers, dave
Good day. This bug occurs because field *flags* of variable *myAnalysis* is not initialized. And therefore flag PANGO_ANALYSIS_FLAG_NEED_HYPHEN of this field randomly set or clear. Sincerelly yours, Siarhei Abmiotka.
