This might be the problem discussed before about double buffering (but I
haven't used Qt 4.1.2. myself yet). In "src/ipecanvas/ipecanvas.cpp",
can you uncomment the line
(in IpeCanvas::IpeCanvas) and see whether this fixes the problem?
In the next version this will be a user preference (because it seems
impossible to make uniform decision for everyone).

This I haven't seen. If you can reproduce it, please post a bug report.
