Qt5+nvidia on-top dialog boxes turns the entire screen black.

I first thought this bug was related to KF5/Plasma but I can reproduce it with LXQT's "runner".

Basically with kwin or openbox, any qt5 dialog that's on top turns the entire screen black until it loses focus, this applies to KF5's menu, clicking the desktop on plasmashell, krunner, lxqt's runner.

Any ideas?

Re: Qt5+nvidia on-top dialog boxes turns the entire screen black.

I also have this problem.  I keep testing plasma5 every time a new version comes out but no luck so far. I have an old Dell Latitude E6410 with an Nvidia GT218M card.

Te be clear let me explain what I see:
- Start plasma 5 (I installed package plasma-meta)
- I see the KDE splash screen and everything looks good
- Then I get a black screen with a mouse pointer. Sometimes when I click on the KDE menu the whole display flickers to life and immediately goes black again.

If I start some application like xterm with Alt-F2 (typing in the dark and hoping for the best) then I can see the desktop and everything looks good as long as the xterm has the focus. Clicking anywhere else makes the screen go black again until I refocus the xterm (alt-tab).
