Serious performance problem in Firefox 27.0.1

[motoguru]

Hello again,

I just want to notice that there is a serious performance problem in newest FireFox release (27.0.1). I though that my application fails (I've got many thousands of records in grid) but I've double checked on free version Demo page (infinite scroll) and scroll is reeeeaaallly slow. I've also tried on IE11 and IE11 comparing to FireFox in this version is pure power monster

Hello,

I have the same problem as above - Chrome works better than Firefox 27.0.0.1 but also works slow.

I have a grid with 30 columns and 60 rows.

Please help us because PQ GRID is unusable in Firefox for now.

for performance

virtualX should be true especially if number of columns > 10

and

there should not be computationally time intensive operations in refresh event.

Thanks, it helped a lot but i wanted to use virtualx:true to have the same rows height.

Then either lock (freeze) the column having highest rows or use wrap: false

It works but column name are unreadable, it would be useful to add "title" attribute for TD with column names, than after mouse over we would see full column title.

1) column.title can be html string so you can add title: '<span title="Full title">Full title</span>' in column definitions.

or

2) use column.minWidth property so that the column doesn't shrink beyond specified minimum width and title displays without cutting off the text.
