Description of issue

Graphical glitches appear after the computer wakes from sleep. They look like large triangles of varied colors and sometimes still display some of the graphical elements behind them. I am no longer able to interact with anything on the screen. I can temporarly regain access by following the temporary fix below. https://i.stack.imgur.com/mdXCr.jpg

Steps to reproduce

Allow computer to go to sleep.
Wake up the computer.
At first it is fine, but after unminimizing a program the graphical glitches appear.

Temporary fix

After glitches appear, I can reset kwin by holding ctrl+alt+f2 (screen goes black) and then ctrl+alt+f1. This reset fixes the glitches, but once another program is unminimized the glitches reappear. Once a particular program has been unminimized once, it no longer produces the glitch if minimized and unminimized again. If the computer is restarted the glitches do not occur until after waking from sleep again.

Hello, I'm facing the exact same issue. I'm using Manjaro KDE on Nvidia 1080Ti. I think this is specifically an Nvidia issue, possibly related to KDE.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
