Description Mina 2018-06-22 17:46:08 UTC

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?

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Plasma 5.25 or 5.26?

If it is, please change the status to CONFIRMED when replying. If not, or if you can't because you no longer use this setup, you can change the status to RESOLVED WORKSFORME. Thanks a lot!
