Is there any possibility to back to old behaviour of this function via settings?

I am not sure if it is web page issue or I found memory leak which consumes whole RAM until my PC (Windows 7 64-bit become unresponsive). Can somebody please confirm that? The problem occurs on the following page:

PS. Ads blocking was disabled in my case, otherwise this page will not display properly.

PiP window is jumping, at least on youtube. If you move the PiP window that it is partially hidden (is located partially beyond screen), then after a couple of minutes it changes its location.

I found a bug. If I turn off second screen in my laptop (the external one) and switch to single screen (the on that is built in my laptop), then opera reopens. BTW, this occurs when external screen works as main screen when connected, I don't know what happens in other cases.

@leocg: The issue I observed is way more random and similar but not the same. Anyway I'll wait for 88 version and check if that will help.

There is a bug connected with history. If you close Opera and reopen it, then sometimes it either not open tabs that were opened just before closing (I can see only speed dial) or ot opens tabs that were opened in the past but not just before last time closing. It happens to me circa once per week. Browsing in incognito mode and closing incognito window also has impact on the tabs in non-incognito mode and it can cause such improper behaviour in non-incognito window.

Looks like you've broken FTP handling. FTP pages are blank.

@johnd78: Thanks bro!

Is there any way to disable the new extra window showing thumbnails when trying to upload files?

In this version there is next 2 things broken: 1) ctrl+g doesn't work anymore (so far it was functioning as ctrl+f of a last searched phrase), 2) after writing web URL or search phrase in URL bar and pressing displayed (prompted) address using left mouse button (my enter key doesn't work so I don't know how it works when pressing enter), given page starts to load and then opera goes back to speed dial page.

BTW, Opera has a bug in URL bar list which annoys me quite a bit when I'm using browser a little bit faster. When you click the URL bar, the addresses from history and prompts appear and then, when you hover over the list, then you have to sometimes hover over multiple times as at first it doesn't recognize properly the position of cursor and highlights bad addressess.

I also think that the green padlock was way better as you could quickly check if given page is secure (I know that in fact that's simplification but still way better). And the protocol prefix (like http/https) displaying was also nice.
