Короче, вот эта картинка помогла, хотя я так вроде бы пробовал.

Галочка снята — работает.

There is nothing aroundto look at: where is solution?
I don`t have pop-up windows of Downloads in the right top corner and Copy-Search above selected text.
Why? When will this bag be fixed?

Mobile Intel(R) 965 Express Chipset Family (Microsoft Corporation - WDDM 1.1) version 8.15.10.2697 of 01.10.2012 — MicroSofts driver on Intels equipment(Intel "finished interactive support") This driver ceases to display Download and Copy-Search pop-ups after Creators update. There was no problem before updating.

Mobile Intel(R) 965 Express Chipset Family version 7.14.10.1244 of 30.03.2007 — Intel`s driver from disk to my notebook. This works correctly with Opera, but n ot with Windows 10: https://imgdepo.com/show/10689161

So most likely problem caused by Microsoft. May be they insensibly finishing support of antient comps.
But, probably, Opera developers (developers of the most convenient browser) could fix this minor inconvinience, bypass this slippery place in driver-operational system interaction?

Please, help! Fix it!

"(Microsoft Corporation - WDDM 1.1)" this is written in properties of device. Which your drivers works correcrtly?
My old drivers caused such problem: https://imgdepo.com/show/10689161
so I use new drivers, which blocked pop-up windows, but today I found signes, that the matter shifted from tehe dead point: https://imgdepo.com/show/10689160

This works correctly with Opera, but I began to remember the old bluescreen sometimes.

Excuse me, was this problem with pop-up Download and Copy-Search windows solved?
After rolling back video-drivers to OEM version - alles gut. But that is rough solution of the problem.

Problem appeared after installation of Windows Creators Update.
After Drivers rollback to old OEM version pop-up windows "Downloads", "Copy-Search" operate correctly.
Opera 45.0.2552.869 Stable (russian)
Windows 10 32-bit 1703 15063 (Creators Update)
Driver Intel 965 Express Chipset Family:
Microsoft - WDDM 1.1 v 8.15 (2012) - incorrect operation after Updating Windows 10;
OEM v 7.14 (2006) - correct operation before and after.
Could you advice me where should I ask for help: Opera, Microsoft, Intel?
Problem is actual https://forums.opera.com/topic/20474/не-работает-кнопка-загрузки-после-обновление-сборки-windows-10

Вопрос, собственно, к разработчикам Оперы как продолжение темы. Поскольку не работает корректно Опера 42 и 44 на более новых, чем заводские на диске, драйверах после установки на windows обновления Творцов, то становится непонятно, что не поддерживавет обновлённая windows: оперу или драйвера. Или это Опера не адптировалась к новому обновлению и стала некорректно работать на более новых драйверах?

Аналогичная проблема. Дело оказалось в драйверах видеоадаптера. Принудительно установил старые драйвера (с фирменного диска, который шёл с оборудованием), стали корректно появляться всплывающие окна при нажатии кнопки "Загрузки" в правом верхнем углу, при выделении текста ("Поиск-Копировать"). После возврата новых драйверов эти всплывающие окна снова не работают. Опера 44 Stable, Windows 10 32-bit 1703 15063 (Creators). На необновлённой системе всё работало и с теми же новыми драйверами.
