Currently , the tooltip instantly pop up once you hover over an element, even if you just travel with the mouse between two distant elements. At least on OSX there is always a performance hit (waveform stutter), if the tooltip of the next element pops up.
Symptoms are similar to lp:685795 and lp:872003

You can work around that by disabling tooltips, but that won`t help many users (if they even find the option).

I thought about delaying the tooltip display on mouse-over. Mouse rest over an element more than X ms = tooltip displays. Common are delays of about 500ms, but that is too long imo.

Having a delay for the tool-tip would be really great. I get annoyed
everytime with the huge tooltips when I test mixxx.

Just a delay of .2s or similar would already help.

Max, can you confirm the negative performance impact ( re: bug title) on your system?

Nope I can't reproduce this on debian 8 with a thinkpad t440s.

I can not confirm that with Mixxx 2.4-beta. Lets close it.
