Performance improvements for 11.62 (Tunny)
By Ruarí Ødegaardruario. Thursday, February 23, 2012 10:51:20 AM
Tips to make it easier to test and give feedback:-
Compare against 11.61, not 12.00
(use the install instructions in the links below to install alongside stable Opera) -
Delete cache before comparing
(otherwise you might be comparing cached and non-cached content) -
Test multiple times and ignore minor differences
(the nature of the internet means there will always be some fluctuation) -
We are only interested in faster or slower
(loading at roughly the same speed is not a problem) -
Mention your location and the page you tested against when giving feedback
(websites hosted in the same country as you will tend to have lower latency)

WARNING: This is a development snapshot: It contains the latest changes, but may also have severe known issues, including crashes, and data loss situations. In fact, it may not work at all.

if yes: very annoying!!! Happens in all Opera versions! You can reload the page as often as you want, you'll always see it. Hopefully it will be fixed one day
but apart from that, a very nice & fast build

Yes, that's it - and it's really ugly!! Related to this issue go to www.ameeradance.com and just click about the menus, the page "flashes" to white each time before drawing. The "redraw after xx seconds" option is being ignored and it's ugly as hell when navigating around sites. You can see the same flashing at www.cwc-services.com and www.tregathenan.co.ukNote however that it happens on a bunch of - but not all - sites. The trouble is that it's affecting many sites and makes the browsing experience quite visually nasty. No such issues in Chrome or FF. Interestingly, the last Opera build to not have this issue was the one before the big M2 update.
If you go to demo.yootheme.com and pick a template from the selector, and choose from the menus, you'll notice here and there that Opera also gets the layout completely wrong.. dropdown menus extend all the way to the right and DIVs are incorrectly wrapping. Reloading the same link by clicking it again fixes the layout issues, so this is defo an Opera issue and note a site compatibility thing. There's something wrong with Opera's layout and drawing engine.
Finally - and also related - often hitting "back" causes blanking and redrawing in the same ugly way. Gone, on many sites, is the whizzy RAM-based caching that we used to enjoy for back/forward history navigation. I understand that some of this has to do with Javascripts, but the flashing-redrawing behaviour is ugly and slow.

I'm an experienced programmer and my feeling is that this relates to the rendering/drawing logic rather than the page-loading logic. Though of course, having not seen the source, I'm just guessing

@ W7x64
Anyone?
Please test: just go to new tab and reload, when you have dials on it incl. extension dials.
Since many builds

Every time i click on a magnet link in the http://thepiratebay.se/browse/302 site the browser crashes!!!
The magnet link is the one with the small red magnet.
It used to work with prior versions of Opera...
Another issue with bookmarks
In this release sometimes bookmarks, after sync, get messed up, i.e. recently used ones go to top of bookmark list and one needs to rearrange them by hand... very annoying

edit: and sometimes the icons can not be catched. Confirmed?

-> no change of mouse icon from "arrow" (standard) to "pointing hand" (open link)
PS: I checked masking as IE or FF. Also deactivated content blocking (both: native and extension).
OS: W7x64
Working on: trident, gecko and webkit (lunascape 6.0)
Anyone?

sometimes get this icon: http://img803.imageshack.us/img803/2475/d0142090ead34997a8b9900.png - (tonspion.de, golem.de, ...)
Why doesn't Opera just catches the icon from bookmarks?
W7x64
Anyone?
