The laptop is an HP envy x360. For this laptop if I set the refresh rate to be 59.93Hz I can't notice any flickering, but for 60.01Hz or 40.01Hz I can notice flickering. On startup the refresh rate is set to "auto", but I don't notice any flickering. Then when I connect an HDMI cable to extend my display to a second monitor I can notice flickering. When I look at the refresh rate, it's set to Auto. So I set it to 59.93 and the flickering goes away. (This doesn't affect the extended monitor in any way). If I disconnect (or also reconnect) the HDMI cable, the refresh rate is changed to auto and I can see flickering.
Which version of Plasma are you using?
