This is exactly what happens in Windows for me, what did you expect to happen?
My expectance was the line's contents shouldn't disappear, but if you say this happens in Windows, too, then this is just a minor inconvenience (even if it was a WINE problem), therefore already forgotten.
As for the others, well, if you want a demo project for the 1st bug, I attached some mockup schematic (demo.asc) that needs zooming in order to see the slow-down caused by the panning, but in order to actually see the effect you'll have to use the newer versions of wine, from 1.5.13 (including), up.
Now that I'm writing these, I realize I haven't said what hardware/software I have, so here it is: HP Pavilion dv7-1053ez (C2D P8400, no overclock/undervoltage, 4GB RAM DDR2, GeForce 9600M GT 512MB RAM DDR2) which runs Linux Mint 13 x64 (Gnome, but I'm using Xfce 4.10 ppa), with ppa for WINE from http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu . Currently, I have wine1.5-amd64_1.5.12-0ubuntu1_amd64 , downgraded everytime a newer version came along because of the panning thing.
Lastly, about the traces left behind, now that you say it doesn't happen with a different graphic card, it may well be because of nVidia's drivers, so I'm at their mercy (I use Xfce's compositing feature for the shadows -- they make working with unmaximized windows much easier for me -- but it doesn't affect the result).
