We have developed a web application that displays quite a lot of data in a somewhat fancy table interface. I can’t show the page, but it has a rather large table inside a fixed positional element with some images (mostly icons smaller than 2 KB, PNG with alpha transparency and no more than 30 different images).
It is not so heavy, less than 1000 elements per page. It was developed primarily in Chrome, and works flawlessly in Chrome. Both IE11 and IE10.
But when it comes to IE9, it happens:
Yes, it is IE11 because it offers decent analytic tools. I use IE9 emulation, but the same reaction does not work with IE10 in IE9 mode and with native IE9 with high CPU consumption but stable memory usage.
In a milder sense, this also happens in IE8:
But repainting takes much less time (maybe it repaints smaller parts of the page?), And the reaction is not compromised.
As you can see, there is no script, just some random garbage collection. In IE10, IE11, and Chrome, repainting is not used there.

IE9 ( IE8)?
