I installed the newest Opera (64.0.3417.61) and problem disappeared for now. If wont help I'll make test. Thank You

I dont have Bitdefender, Sandboxie and IDM - actually I dont know even whats this

Im testing...

Well, the problem is that I do not play anything,
I don't have a connected monitor/s
I am the only user
I don't change the resolution
I am testing the opera closing properly,
the system is clean, formatted at the end of December
I have a new computer, updated Windows 10
I reinstalled a new stable opera clean (v 67)
and once in 10 times the opera opens minimized
I do not know why!!!?

@leocg Exactly.

@leocg Yes, I have two keyboards - default & one more.

@leocg

Ive got just one Opera on android:
Version: 81.6.4292.79147

@leocg : Unfortunately not. My keyboard everywhere looks different than that in Opera.

I can see that Ive got just one motive of keyborad at Opera on android - light or dark. Can I change it for completely different e.g. something with wider space-key?
Thx

That's understandable since Opera doesn't get to shut down properly. - OK, but what about closing Opera without shutdown computer when I close it properly? (Win 10) It doesnt remember that should open in maximalize window. (Why?)
