Hello everybody,
I am new to KDE. The installation of Manjaro KDE Plasma is easily on my PC.

But I installed Nvidia driver, then tooltip does not show graphic of window.
See the screenshot:


The tooltip has no issue without Nvidia driver.
How should I properly configure Nvidia driver for KDE and KDE settings?

KDE Plasma version 5.12.4
Intel i7-4770
Nvidia Geforce 760 GTX
Nvidia driver version 390.48

Hi,

can you post the output of lspci -k|grep VGA -A2 and also let us know with version of the Nvidia driver you have installed?

I am asking because there are no KDE specific settings I am aware of and am therefore assuming that it is an issue with the card and the driver.

known, can be fixed by reverting the commit, currently people try to solve it properly.
Driver version and card very likely to be irrelevant, if relevant, please add to the bug report instead.

But as far as I can see, most are affected, and both nvidia and nouveau.

Thanks for the info, K-Fuchs!
