Hello, this issue persists since 2 or 3 months (running KDE Plasma on Linux Manjaro):
after booting to the KDE Plasma desktop, double-clicking the icons will not start the respective applications (in Dolphin the doubleklick works fine !)
Also not when using a clean, fresh Manjaro KDE install, or a brand new mouse. What I could find out until now: left klicking the networksymbol in the taskbar, or the loudspeaker-icon, then their respective panels pop up. Performing this action get the double-click on the desktop icons working back again !!
So: I presume something does not initialize well at the very start of KDE Plasma, but does with a simple left-klick on one of those 2 icons in the KDE taskbar.
Any idea which graphical thing get’s his initialization when using the network/audio icon in the taskbar ?
Are you using a high refresh rate screen and/or an AMD or NVIDIA GPU?
Yes. RTX 3070 with an 170Hz Gigabyte M27Q.
But: this combo worked in the past. I do not remember well, but since 'round 2 or 3 month the described topic arised.
Aha, then this is 419421 – QML timers go too fast with multi-threaded render loop when using any high refresh rate screens on X11 when using FOSS amdgpu drivers.
It’s a known issue with that combination of factors. A workaround can be found at 419421 – QML timers go too fast with multi-threaded render loop when using any high refresh rate screens on X11 when using FOSS amdgpu drivers. And it’s already fixed in Plasma 6.
Hello Nate, thanks for your reply. Glad to hear it will be solved with Plasma6. When will this be deployed ? Cause I unfortunately cannot understand(from what is written in the linked forum entries) what to change in order to get it work on Plasma 5.xx
Plasma 6 will be released late this year or early next year.
To apply the workaround, search for “renderer” in KRunner or Kickoff and open the top entry. In that window, change “Render loop” from “Automatic” to “Basic”.
Hi Nate, that helped a lot ! Thanks for your explanation, now that doubleklick works again !
One question left in my mind: by setting it to “Basic”, will that stay there after the next update ? (I’m on Manjaro).
