[B3/RC1/RC2] Weird stuff happening on Chrome 18/19

[morfeusz]

I have the same problem.
All my aplication`s layout is broken on chrome 18 (big viewport with many panels).
I back to 4.0.7 and it`s work now.
The suggestion about width and height returned NaN, not working on my case.

For me is working fine now.
Perhaps you are using some specific functionality. Can you build a simple example with this bug?
I can try help you.

Ok.
I have sample - it`s very simple:

To reproduce "weird stuff" (on chrome 18/19):
1. collapse left panel
2. expand left panel
3. repeat to 10 times

The extjs-4.1.0-rc1/src/layout/ContextItem.js: is fixed like you suggest but it`s not working on my case

Chrome version 18.0.1025.142 is messing up the layout. Application is totally broken unworkable.

Panel resize or whatever, and bang.

I can reproduce the issue in your example, but I don't see the fix in your ext-all.js file.

[rhapsodyv]

I have tested your example here and the problem doesn't happens anymore. It's happening to you because you have updated the ContextItem.js, but you are using an outdated ext-all.js.

The original extall.js already have ALL extjs files. Updating the file extjs-4.1.0-rc1/src/layout/ContextItem.js, doesn't change the content of ext-all.js, unless you do this.
You have 2 options: create an updated ext-all.js after updating ContextItem.js or use ext.js (or ext-debug.js) - it will load all dependencies dynamically.

Thank you very much - now it`s working.

Can someone post their extjs-all with the fix?

[rhapsodyv]

The problem continues in the RC2. The same fix solves the problem.

It has to do with the new Min en Max implementation in the v8 engine http://www.sencha.com/forum/showthre...ms-in-chrome18

But besides that, there is an enormous performance loss in Chrome. If a page contains a grid with some amount of records and I switch a tab on tabpanel on the same page, it takes seconds. It all depends on the amount of records in the grid. With 30 record it switches quickly, with 300 records it takes at least 2-4 seconds to switch a tab.
