Description tkaitchuck 2009-09-01 08:51:55 UTC

Version:            (using KDE 4.3.0)
OS:                Linux
Installed from:    SuSE RPMs

The wobbly windows allows advanced settings where one can set each of the stiffness, drag, and move factor individually. However if these are all set to their maximum value, once moved windows will never stop wobbling rendering them all but useless. The value of stiffness should be capped so that this cannot occur.

The physics involved in wobbly windows is quite complex and if you modify the values manually you can create non-realistic/unstable motions. Unfortunately these values cannot be capped as it would prevent some realistic/stable motions from being able to be simulated.

The advanced settings are there for people that understand solid/fluid mechanics or for people that just want to experiment. That's why the settings are disabled by default and a "basic mode" is provided for everybody else.

Hi,

first I'd like to apoligize for submitting the same report (Bug 209514) twice... When it didn't show up in the "My Bugs" list, I thought something had gone wrong when submitting it... (I didn't realise how fast you guys were marking duplicates ;-))

Anyhow, if the pattern I described in my report proves correct, wouldn't that make it possible to cap the stiffness value at a threshold that depends on the move factor value in such a way that only the unstable combinations are capped?

So maybe this issue should be reopened...

I have this problem, in Ubuntu with KDE 4.3.

I can't even restore the settings. The window to change the settings wobbles so hard that I can't press the button on it to change the settings back. And it never stops.

Here's the problematic values:

[Effect-Wobbly]
AdvancedMode=true
Drag=50
MoveFactor=25
MoveWobble=true
ResizeWobble=true
Settings=Auto
Stiffness=50


I'd like to vote for reopening this bug. Having "confusing" windows behaviour is one thing. But being unable to restore the setting (being unable to do ANYTHING in fact) due to not being able to USE a window anymore, is a big problem imho!

This was marked as INTENTIONAL? LMAO

Comment 9 The Feren OS Dev 2021-03-15 01:55:51 UTC

no offence by the way, I just found this earlier because someone else showed me it... fair enough for closing it the way you did... it's just... this 'feature' is... something.


Probably should be reopened though for its potential epilepsy problems due to the flashing that can occur.
