Flickering application

[denis.guenther]

Hi there,

i found a problem using extjs under win10 and ie11 and hope someone could help me with that:

• Open: https://examples.sencha.com/extjs/6....min-dashboard/
• Drag the window a little bit smaller so that there is a scroll bar on the right side
• Switch between the navigation "FAQ" and "Widgets"
• -> The app starts to flicker

What i found so far: This seems to be only a problem under win10. Using win7 and IE11 nothing happens. Also edge and chrome does not make any trouble. I also tested this with other extjs versions and asked friends to verify this outside of my environment - same result.

Does anybody know how this could be fixed?

Thanks!
Denis

i don't get this on any browser in win10 pro. (IE, edge, opera, chrome)

sounds like a display driver issue to me or could be a browser extension.

That's what i thought first and asked a friend to verify this outside of my companies environment.
Maybe this is some kind of bad luck that or the drivers they are using are very similar, i could ask some other people to check this.

Thanks

I attached a gif showing the problem. Had to wrap in a zip cause uploaded gifs seems to be converted in jpegs

Maybe this depends on the ie version - mine is 11.1155.15063.0 on win10 and 11.0.9600.19035 on win7. Which one did you use?

I just confirmed this on another win10 computer in IE 11.165.17134.0

it's like the whole page is redrawing on load

Now that Edge is stable (and faster and lighter than chrome) I'd be advising clients/your company to use that.
