scrolling with mouse wheel freezes
« on: June 20, 2022, 11:53:06 pm »
Hello,

I have a grid with 200 rows, when I scroll with scrollbar it is perfectly smooth. But when scrolling with mouse wheel, it scroll a bunch of rows, then freezes for a while, then when I keep scrolling the wheel it moves afterwards a next portion. No obvious reason, no other async calls, etc. VirtualX, virtualY enabled.
Do you have an idea what could be cause?

PQ8, bootstrap4

Thanks,
Jan

Mentioned issue is observed in Chrome browser on Windows OS.

This has been fixed in v8.4.0

Hello,

I can confirm this behavior only in chrome, edge works well.
Unfortunately upgrade to 8.4.0 have not solved the problem.

Any other suggestion is welcome.
