Scheduler 2.2 - Mouse wheel scrolling performance issue on bigdataset demo
Posted: Mon Jul 22, 2019 5:26 pm
On the bigdataset demo, scrolling upwards using the mouse wheel is very sluggish when near the top of the list, although performance is fine when scrolling upwards further down the list.
Steps to reproduce:
1. Load the bigdataset demo
2. Turn the mouse wheel down one full turn
3. Count number of upward mouse turns required to return to the top of the list. For me, one down turn requires 3-5 upward turns to return to the start of the list.
Expected outcome:
I'd expect 1 turn down to only need 1 turn upwards to return to the start of the list. If you repeat the above but start already scrolled to have resource #50 at the top of the screen, one turn down, one turn up returns you to the same position as you started.
Affected browsers:
I've tested in Chrome 75 and Firefox 68.
Scheduler version tested:
Scheduler 2.2
