1. bad scroll performance when text is highlighted from search box
2. "remember password?" question bar will move site not only downs, but also left a little bit.

In the Flexbox example.

While selecting some text in the middle of the boxes, and you have the cursor between two words in the text, the selection seems to grab the text below the flexbox, the Lorem ipsum text.

This does not happen if you scroll the page to the bottom before selecting.

Win8 32bit

If you press Ctrl+F again before the find menu is done transitioning, it will start to transition again from the beginning.

Is flash broken on linux?

If you use Ctrl+F the find menu will stay, if it looses focus.
If you use .(dot) the menu will stay for ~3 seconds before disappearing, if it has lost focus.

The ~3 seconds is after you pressed dot, not after it looses focus. This seems like a weird behavior.

Don't know if any of this is intentional or not.

Flexbox is my most favorite CSS3 feature, thank you for implementing it

Now the last really noticeably missing CSS3 feature in Opera is the "calc" function.

Oh, and don't forget about -o-user-select. Now even IE10 has it

Loading time for some pages are very long, so: www.computerbase.de ; www.tomshardware.de/news or www.anandtech.com . I must stop and reload this pages. I've general Cache, Java script, plugins, Geolocation and Cookies deactivated. Allowing of plugins specific to the page not, only globally.
Not so in Opera 11.64/Build 1403.
Installed is only the skin "classica__12_xx_-12_50_1497".

Opera does not find the plug-in.

Performance is worst on linux.
Many pages cause high cpu usage while loading is in progress.
When loading is finished, cpu usage goes to normal level.
Scrolling performance is worst too.
Several random NSLs too.

Works fine here Win7x64

Worked fine for me too in earlier versions and snapshots. But since the last view snapshots it doesn't work anymore. Tried also a clean profile.
To make it work now I first have to clean cache which I hadn't to do before when it was enough to just reload the page.

WinXP

Edit: I just saw, only a certain page is affected of this. If you edit the source of http://www.fca-liveticker.de/ticker_inline.html and for example remove one or more frames, you probably can reproduce it.

opera still crashes when opening dragonfly and is unable to produce a crashlog.

Confirmed.

Why does F11 (back from full screen mode) not work while "Press ESC to exit full screen mode" is on the screen? Bug or intentional?

The Arrow-Down key still does not seem to work in the address-bar on FreeBSD... But at least it's no longer mapped to 'Enter', that makes this build only annoying and not unusable...

After every upgrade, Opera AdBlock extension stops from working. I don't know about the other extensions as I only have this one installed on Opera Next.

The solution is to reinstall the extension.

white flash still present. Win 7/8, Opera 32bit

But my point in asking that was "Is yours also set on 3, and if so, does setting it on the usual 1 get things back to what you expect?".

No mention of that Linux (Ctrl+)Shift+Tab issue, so probably not fixed yet ...

In Opera not work download any script if this is save in other domain. I see this problem in http://gumtree.pl because in any ads cannot send attachment but solution is easy (download http://include.classistatic.com/include/e793_5/c3js/classifieds/rel1/shared_pages/flashChecker-min.js this script and add him as userscript) .

There are still some issues with Imagus - when you hover zoom and image and move the cursor a bit, it smudges all over the place. Plus, DSK-372481 (see http://my.opera.com/community/forums/topic.dml?id=1504912)

Confirmed for that specific link. I suppose they only allow access for Firefox clients to that path. But on a general basis, ftp seems to work as it should in build 1620.

Copied this from my post in the previous build -

Opera crashes on this website address - www.kbb.com/whats-my-car-worth

Opera fails to create a crash log when it crashes for the above site.
Opera x64, Windows 7, HWA on.

Also for Chase bank site (chase.com), after entering the log in details it will not load the account splash page. You always have to reload the page, then it loads fine.

Additionally, in the previous build & this build all the graphics are broken on www.xda-developers.com

After writing a message in the chat on gmail (or g+), the cpu goes over 50% and only close the tab stop it. In opera:cpu the usage is about 2-3%.
Disabling SPDY fix the problem.

Someone in Opera is considering this? I'm reporting this since SPDY was introduced.

(Windows 8 rp x64, x64 build, hwa off)
