Can I add my voice to those saying that I value the 'Recently Closed Tabs' feature and am grateful to #burnout426 for explaining how to restore it. I hope the developers will take note of all these comments.

I am in exactly the same position. I have tried uninstalling and reinstalling. Made sure it is installed as administrator as well as user. I think it is a bug they have introduced. For me, this behaviour just started appearing - I had not done anything to my machine to provoke it.

@burnout426 Thank you. This works perfectly for me. I really don't believe the Custom New Tab extension was malware whatever Opera says. I was originally attracted to Opera because of its many customisations - the Chrome version has never matched up to the old Presto one and it is getting worse, while Vivaldi is getting more customisable. I think we are almost at the point where Vivaldi is better apart from the lack of VPN.

No, it is something introduced in Opera 45 which was not there in Opera 44.

I tried installing Opera 44.0.2510.1457 in a clean virtual machine running Windows 7 (64) with internet disconnected to stop auto update. Opera opens normally going straight from the desktop to Opera's home page (in my case Google).

I then reconnected internet and allowed Opera to update itself to the latest version 45.0.2552.881. When you open Opera, you now get a transition where the whole of the Opera window is semi-transparent before moving to its normal appearance as in the Opera 44 image above. The screenshot below captures it in this transitional phase. Opening in a window rather than full-screen makes clearer what is happening.

The only thing that has changed is the update from Opera 44 to Opera 45, which establishes that this is an effect introduced by Opera 45 and nothing to do with my profile, graphics card or system setup.

Can this be looked at by Opera developers?

I am now a little clearer what it is I'm seeing when Opera opens. With an aero theme, the bar at the top of the Opera window is always semi-transparent so I can see part of what is underneath. Now when I open Opera there is a period of time between a fraction of a second and three seconds when it is as if Opera displays a blank window in semi-transparent mode with everything underneath showing through but blurred. Turning off aero removes the problem, although I want to keep aero on. Turning off hardware acceleration in Opera makes no difference. The effect is there when opening a private window as well as when opening Opera from scratch. I'm pretty sure its not a profile problem. What I will try next is reverting to a previous version of Opera but using my current profile. It is my belief that this effect only appeared in very recent versions of Opera and this will help to establish this.

Other browsers (Firefox, IE, Chrome) may take a second or two to open, but when they open they go straight to the normal appearance with just the menu bar semi-transparent. They do not go through this intermediate stage where the entire screen goes blurred.

I have cleared all downloads, although I do not believe my screenshots showed a red progress indicator. I am still experiencing this strange transition effect when opening Opera, but not when opening any other program.

Here are the screen shots showing the transition. The blue wash and diagonal bars are superimposed over whatever was on the screen and are replaced after 1-3 seconds by my normal home page in Opera.

I am using Opera 45.0.2552.812 with Windows 7 (64 bit). In the latest version of Opera, I now have a strange visual effect when opening Opera. Whatever was on the screen is covered by diagonal blue translucent bars for anywhere between 1 second and 3 seconds before Opera opens. I would attach screen prints but can't find a facility to do this. This did not happen before and does not happen when opening any other program. If this is a deliberate feature, please remove it as it is annoying.
