Description
I'm seeing multiple graphical glitches using a QGraphicsProxyWidget on a high-DPI screen in Qt 5.3. One easily-reproduced example: when embedding a QLineEdit, the cursor blink causes an entire character to be cleared and not properly redrawn.
Reverting to Qt 4.8 causes these issues to go away, although then QTBUG-39206 occurs.
Attached is a minimal sample program and a screencap gif showing the issue.
