QTwebkit doesn't handle Flash correctly

First of all: I don't know the correct version: It is the package qtwebkit-2.3.2-1 and I have no idea how this translates into your versioning ....

1. Flash doesn't scale when pressing "ctrl +" in webkit based browsers (Konqueror, rekonq, epiphany)
2. When using Nvidia drivers flash switches red and blue colour (blue tint bug) though other browsers (firefox, opera, chromium) do not have this problem

It's a showstopper as none of the webkit-based browsers works correctly on any flash content ...
