All this time, I just thought it was slow

I have the task manager set up like probably most of you do, to show a preview of the window when I hover the icon.

There’s a significant delay between when I hover, and when I see the thing I came for. For the past few years, I have been operating under the impression that Plasma just took that long, to generate the preview.

No, it’s an entirely artificial delay. You can bring it down to 1 millisecond like so:

kwriteconfig6 --file ~/.config/plasmarc --group PlasmaToolTips --key Delay 1

Or some other number that feels nice and snappy but not too crazy like 150.
0 will disable all tooltips, so you probably don’t want that.

If you try the above and don’t like it this will get you back to default.

kwriteconfig6 --file ~/.config/plasmarc --group PlasmaToolTips --key Delay --delete

I presume this is one of those “yeh didn’t you know?” things, but just in case anyone else didn’t know… Now ya know.

FWIW I think this default setting of 700ms(!) delay gives a terrible impression of Plasma’s performance and should be revisited. But that’s not what this thread is for, I ain’t tryin to fix it, just trying to share the love :wink:

By the way, if anyone else knows of any other spots like this where delays are added ‘for taste’ then please do share :slight_smile:

wow, amazing! You save my life! This is a problem has been troubling me for a long time, to the point where I even considered turning to Cinnamon. Btw, could you tell me where to find related documents?

I wish! I spent about an hour searching to find a setting, then digging through the task manager’s source code trying to find this, and found nothing. It was then that it hit me - this isn’t task manager’s delay, this is the same time everything is delayed for. I moved my mouse around the screen and the realisation that the various delays were all the exact same timespan hit me. I bet this is plasma-wide. So I searched for that, and found a post on reddit from the ever-helpful Zren, with this tip.

I wonder if there’s a list somewhere of all the hidden settings… Like a KDE config file schema or something?
