    Description

      Hi. We are building a large software with Qt 4.8.4_Win32 + Visual Stuido 2010. Few months ago, we found continue memory usage rising when we use QPainter.drawText() in QThread. Then we made a program(as attachment) and make sure there is a memory leak. Here is screen print. We tried 4.8.4 and 4.8.5 and result is the same. Thanks for helping us.
