Description Markus Elfring 2008-02-04 14:28:03 UTC

Version:            (using KDE 4.0.0)
Installed from:    SuSE RPMs
OS:                Linux

It can happen that the analog clock will follow the mouse pointer a bit later while I am rotating this widget. There is not always an immediate reaction as I would expect.
Will any fine-tuning be needed for better responsiveness of such a little application?

this is usually caused by a composition manager not updating the window quickly enough; we also have a small pixel delay to avoid accidental rotations. it is what it is ...

Comment 2 Markus Elfring 2008-02-13 10:17:54 UTC

How are the chances to improve the execution speed of a composition manager like KWin 4.x?

Is the pixel delay for "accident prevention" configurable?

With 4.1 just around the corner, it's time to close off 4.0 bugs. In the off chance that I'm wrong in believing this to be fixed in 4.1, please reopen. :)

Specifically, resizing and rotation are now separate functions (can't remember if they were or not in 4.0.0). Rotation snaps at 90 degree angles but the reaction is immediate otherwise.

I have still noticed the small rotation delay in KDE 4.0.4 sometimes.

I would prefer that this issue will be only closed if the responsiveness was completely improved.

in current trunk, it's absolutely smooth unless something else starts taking the cpu. i don't think we can get it very much smoother than it is now.
