When trying to move a window through left click and move on titlebar in an Aurorae theme, the movement is too long compared to other decorations.
Steps to reproduce:
1. Select an Aurorae theme
2. Left click title bar and hold
3. move mouse
Window starts to move once the drag distance has passed
The window starts to move only after the drag time has passed that is after quite a lot of moved pixels.

Do not accept left mouse press events on titlebar in Aurorae
Accepting the mouse events breaks moving the window by dragging
the title bar. The reason is that it eats the mouse event and
by that never reaches KWin core to perform the movement.
Other mouse buttons need to be accepted for handling the window
operations. Also we need to listen in general to left mouse
button for the double click operation.

Hey, I've the very same effect not only on window decorations but for every drag using kde 4.9.3..
Is this the same problem or what?
How's drag performance when you suspend the compositor? (shift+alt+f12)
It's the same when I disable the compositor.. I've also tried to set drag start delay and drag start distance, these are also does nothing.
It only happens with my external mouse, drag works fine with my touchpad.
It's the same in every app (qt / gtk) and the decoration
Should I report a new bug?
Thanks for the help!

That would be most relevant and point the X11 input driver.
Alt+LeftMouseButton dragging is equally slow, i assume?
Tried replacing the WM, eg. (if installed) "openbox --replace&"?

Yes, alt dragging is also slow..
When I switch to metacity its also slow..
But, when I start a gnome or gnome failsafe session it works correctly
Ok, this is a completely unrelated issue.
Please gather some information (esp. cpu load) when dragging, ideally make a video and head over to forum.kde.org (Workspace/KWin is ok for now) so we can first determine what actually is the issue, then what's causing it (apparently not kwin) and then deal with it w/o further spamming this bug.
