Created attachment 62892 [details] Scans of printout and scrennshots of LO Calc 3.3.4 and 3.5.4 I have printed a page in Calc 3.5.4 mit much lines. Every fifth line is double-bordered. In former versions there were two thin double-bordered lines. In 3.5.4 there appeared 2 thick lines. Semms to be about 1.1 mm wide, not 1.1 pt.
Created attachment 62893 [details] Testdocument with zoom 400% - test in Calc 3.3.4 and then in 3.5.4
When saving a document in LO 3.5.4.2 the format of the double-bordered lines will be overwritten with the new, much too big, format of lines. Calc in LO 3.5.4.2 destroys the old format - I have to reformat all tables with double-bordered lines and only to use them in Calc 3.3.4. Set the importance to high and critical - for me Calc 3.5.4.2 is now unusual. Will delete this part of the programm.
Fixed in 3.5.5 by Michael Stahl.
