Held click/drag threshold feels too sensitive, any way to adjust it?

Hey everyone, I posted on cachy’s forum and found people that have the same issue, thought I would also post about it here. I’ll include their posts as well.

My issue is that I keep dragging my tabs on Firefox, the icon of Discord servers or just folders/files all the time when I don’t mean to, it feels like the ‘held click/drag threshold’ is too damn sensitive. This doesn’t happen on Mint nor Windows.

expected behavior : when the mouse is in motion during a fast click on an icon/tab it should only click the icon/tab or the icon/tab shouldn’t move enough to be dragged

observed behavior : when the mouse is in motion during a fast click on an icon/tab it currently drag icon long enough to move them to a new location and it drag tab long enough to create a new window,

the behavior is observed only on cachyos using kde. i tested on windows and it worked as described in expected behavior.

I’ve also been having this issue. I’ve only experienced this on CachyOS, not on Windows or other Linux version (with both the same and different DE’s). I’ve used two different Pulsar mice so if it’s a hardware issue then they’re both affected. What I do know, is it’s absolutely not user error.

I suggest that the drag threshold is set (I think maybe 6-10 pixels’) in code now, not revealed to settings after the migration to libinput.

Gamers like to flick the mouse - and clicking on the move means there’s a risk of the mouse moving 6 pixels before the click is released = drag function.

TL;DR

Average click might be 80-100ms which is enough for a fast moving cursor to travel over the threshold.

The threshold is no longer adjustable in Plasma settings… so the solution is not to try ‘drive by’ clicking.
