Description
- Run example program
- Choose "Microsoft Print to PDF" or any other non-QT print driver
- Wait for timing results
4 seconds in QT 5.3.1
95 seconds in QT 5.4.1+
The slowness depends on the drawing calls. Drawing lines is 25% slower, while drawing arcs is 2000% slower.
This bug is a show stopper for our software, which prints 25+ pages regularly. Printing time has increased from 45 seconds to 30 minutes in some cases.
