Ok a patch from 1.11 to 1.12 is here:
you need to be at 1.11 first, but theres a new patch page now that explains it:
1.12 Fixed internet update scroll bug
Faster refreshing on scrolling on updates page
Mousewheel support for updates page
Added option to disable composed backdrops
Changed end year statistics to only count the previous year
If you have an older video card and you get corrupted backdrops, you can disable the advanced cleverness under options now.
