            Bug ID: 483575
           Summary: Delay time between click and menu appearing
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: openSUSE
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general

  Target Milestone: ---

SUMMARY
Upon trying Plasma 6.0.2 (and KF6), I noticed that the delay when opening menus
on Qt-based software in KDE - that most of us perceive as lag - can be traced
down to the menus waiting for the button-click animation to end before opening.

Of course, this hinders the feeling of responsiveness of the whole desktop
environment; is it a known behavior?
I could not find anything related to this, maybe I used the wrong keywords.

STEPS TO REPRODUCE
1.  Open a Qt-based application which presents a "slow" animation for
button-clicks, like systemsettings or Discover; 
2.  Click the Hamburger menu
3. Notice the delay between the click and the menu showing up

OBSERVED RESULT
The menu opens when the button-click animation ends.

EXPECTED RESULT
The menu opens upon click, and the animation speed is tuned by the user.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Tumbleweed
(available in About System)
KDE Plasma Version:  6.0.2
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2

ADDITIONAL INFORMATION
I think this is an old issue, but I only noticed the cause today. 
My suggestion is rather noobish: I suppose we have a sequential  .onClick ->
doAnimation -> openMenu  setup in the code, if possible, making the two
instruction parallel could solve the problem.
