[kwin] [Bug 450268] Magic Lamp / Slide effects duration speed should always be controlled by global option
https://bugs.kde.org/show_bug.cgi?id=450268 --- Comment #16 from bastimeyer...@gmail.com --- > No, because it's not a duration. It's this "springiness" constant. Okay, but you have to acknowledge that with the addition of the "springmotion" logic in 00ae7d38939e3e0c3414009f49d1dabb3a6345bd, sliding between desktops and switching activities has become painfully slow, especially the last end of the animation, which is a usability nightmare. Compared to other animations controlled by the global animation scaling factor, the slide animation is about twice as long, which is really bad. The constants either need to be adjusted accordingly, so that the overall animation time matches the one of the previous implementation, or the user should be given a chance to customize them. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=450268 --- Comment #14 from bastimeyer...@gmail.com --- My animation scaling factor currently is 0.7: ``` $ grep AnimationDurationFactor ~/.config/kdeglobals AnimationDurationFactor=0.7071067811865475 ``` Dividing the *constant* value of 200 by the animation duration factor ``` 200.0 / effects->animationTimeFactor() ``` means that the faster I want my desktop's animations to be (lower animation duration factor values), the slower the slide animation will be. And if I set the animation speed to "instant", which means an animation duration factor of 0, kwin crashes because of a division by zero. -- You are receiving this mail because: You are watching all bug changes.

The animation duration of the slide effect seems to be used when switching activities, which is painfully slow. Changing the global animation speed doesn't do anything, but disabling the slide effect does. The slide effect seems to hardcode animation times: https://invent.kde.org/plasma/kwin/-/blob/6af5a5e65112d9b24392efd6be461d3b85c1ef86/src/effects/slide/springmotion.cpp https://invent.kde.org/plasma/kwin/-/blob/6af5a5e65112d9b24392efd6be461d3b85c1ef86/src/effects/slide/slide.cpp#L62-63 -- You are receiving this mail because: You are watching all bug changes.

The right thing to do here is to fix the speed factor of the animation in the code so it has the same speed as all other animations. If it's too slow compared to everything else, then that's the problem. Leaving it up to users to fix problems is not good for anyone.

The problem with the slide animation itself is that it's too slow. Sure, I could increase the global animation speed, but then all other animations would be too fast. Of course, that's just my opinion. How to fix that? Hmm... how about providing an option to control the speed of the slide animation independently from all other animations?

The easing curve was never configurable, and the magic lamp effect still allows for a custom duration. >Windows that overflow to another screen are indeed invisible on that screen >during sliding, which is a bug. I urge Premik to file a bug report about windows disappearing if that wasn't done already. The problem here is what was quoted above. >Now the slide animation takes a hardcoded factor x as long as some other >animation.

If there's a problem with the animation itself, then that should be fixed instead of leaving it up to the user to work around the issue by manually speeding up individual animations or manually choosing the easing curves. Mind you easing curves don't usually change the amount of time it takes for an effect to complete, only the speed of movement within a certain timeframe, so changing it wouldn't have any effect on the amount of time it takes for windows to appear after the animation starts. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=450268 --- Comment #7 from Sebastian E. --- Premik said that the last pixels take too long to scroll. That's the effect of easing, not a bug. The animation slows down towards the end. Windows that overflow to another screen are indeed invisible on that screen during sliding, which is a bug. The defaults Premik is talking about are obviously the easing mode and the duration of animations relative to each other. Now the slide animation takes a hardcoded factor x as long as some other animation. Before, you could at least change the speed of the slide and magic lamp independent of the speed of other effects. Now, the ratio is hardcoded. That's clearly a regression, and yet another step from a sophisticated, un-opinionated DE to a dumbed-down, opinionated DE. Users should be able to override the easing mode and duration of each animation individually. @Premik: The configuration dialog of the slide effect used to have an option for the animation duration, which was removed from the latest release.

The bug that is causing you to have to change the speed of the effect as a workaround is what should be fixed instead. Adding workarounds to bugs in the interface is not optimal. Now, about defaults, can you explain what defaults are you talking about? The default is to follow the global animation speed setting, which is user configurable. What default should be changed here in your opinion? As for the config presets, I don't see how that would help in this case. The point of presets is to quickly change frequently adjusted settings. Individual animation speed is not something the user will change often. Also, there is a big number of effects, so presets couldn't possibly cover all possible combinations of speed settings for each effect. Also, using a preset for each individual effect is no faster than changing the global animation speed slider. Please mind you the point of this bug report is NOT to remove options simply for the sake of removing options. Yes, simplification was used as one of the points for this bug report, but what's really important in this case is how controlling the same setting in multiple places adds to complexity, increases the number of untested configurations and bugs, and also leads to an inconsistent user experience. I'll give you an example: Just recently it was discovered that the blur effect suffers from a similar issue, where disabling the blur effect doesn't disable it in multiple parts of the interface simply because some effects override the blur settings individually, just like the effects here override the global speed setting. Overriding global preferences in individual effects creates problems. It should also be noted that the majority of people will never customize individual animation settings, and even you only found out about that possibility because you needed to work around a bug, otherwise, you'd have never tried to customize that setting. The drawbacks are too big to justify the minimal amount of granularity this offers. -- You are receiving this mail because: You are watching all bug changes.

The user already has the option of disabling those effects entirely if they interrupt their workflow, so, for that usecase, the setting to independently control animation speed is redundant. -- You are receiving this mail because: You are watching all bug changes.
