In 3.0.5 using windows 7-64 and windows vista.
After selecting to use any drafting tool - either arc, circle or ellipse, polyline etc. there are problems with defining the second snap point onwards whether using auto snap or any of the snap tools,the info feedback i.e. End or Middle etc... is flickering or none at all.

1.Center, Point.
2.Define center.
3.Hard to define point, flickering occurs on graphics feedback for label.

I`m guessing this is another Graphic display problem here.

This task depends upon

These are all problems related to the move to the new Qt 4.8 library. It fixes a bunch of things compared to Qt 4.7 but introduces new problems (on Windows only so far).
I won't have time to look into these this week, so you might have to stick with QCAD 3.0.0 for the time being.

QWidget::update() is broken in Qt 4.8 for Windows. QWidget::repaint() results in flickering on some installations (as expectable).

Of course - there is no hurry, its not a problem, just ' playing' around with 3.0.5.
Hope the feedback helps :)

Snapshot 3.0.6 is now online and should fix these types of issues since it's using Qt 4.7.4 again.
