The weird teleport thingy is me not explaining things well in english so i make up some close description. 
Basically, the mouse (when moving or standing still or clicking, doesn’t matter), jumps to the top left part of the screen and depending on if it was clicking that time it jumped, it either shows me all the windows i’m having open, tested both gnome and kde, or when i click on something like a link, it clicks the top left corner giving me mozilla menu. The mouse icon stays where it is, but it is registered that the cursor is at the top left corner. Also, when dragging windows, they go super crazy and jump all over the screen most of the time. Making it nearly impossible to drag them anywhere near where you want them cause most of the time they end up “maximized” because when “dropped” they are dropped to the top left corner, regardless of where the mouse pointer is.
I mostly use KDE, but i’ve tried gnome 3 too…
On KDE disabling certain desktop effects removes the window show, but windows and mouse clicks still jump all over.
On Gnome it’s the same, thee’s an extension that disables the top left hot corner (Link to this extension), but you guessed it… Windows and mouse clicks…
My specs are:
AMD Phenom II 1090t 3.2 GHz (virtualisation enabled in bios)
8 GB ram
Geforce 9600 GT 512 MB RAM
1 TB WD caviar black disk
Desktop resolution 1920x1080
I’m running it in Virtualbox as guest on Win7 host, so it’s way worse than in the normal, non virtual system.
I’ve been discussing it here in this topic (screenshot is here):

And here, where i got the explanation why this is happening:

Sometimes it’s fine, and sometimes this happens every 2 seconds and for that reason it’s impossible to work.
Workarounds don’t work for me so i’m hoping i can “solve” the issue with a previous version. Untill this gets fixed…
The screenshot in the first link (to a openSUSE forum topic) is KDE desktop showing all open windows. This happens automatically of course.
I wanted to record a video of the bug, but all of a sudden it’s very shy about showing up and letting me explain to everyone what’s happening. Ughh… >:(
If i manage to capture some decent evidence of this bug on video i’ll upload it to youtube and show you here, but i don’t have time today anymore for that so it’ll have to wait.
Wish me luck! rotfl!
Yes it’s a very strange bug, but also annoying and i can’t spent more time trying to fix it. It’s enough. :
If 12.1 is still good, supported and getting updates (without updating it to 12.2), i’ll try that one again. Last time i think it worked fine. I’ll download it and try it.
EDIT: I’m using 64 bit suse version. If that plays any role in this bug i don’t know, but it’s worth mentioning.
