"QmlRenderer.exe" high CPU usage (Murals are turned off / not enabled)

[Inphra]

Issue:

- "QmlRenderer.exe" has high CPU usage  (5-15%)

- Due to high CPU usage, CPU cannot clock down to save energy resulting in higher idle temps (~8C)

- Setting framerate of LCD to 1 lowers the processes CPU usage, but not completely  (this is not ideal nor a fix)

- Clean installation (full wipe) did not resolve the issue

- Murals are not enabled and all LEDs are set to a static colour

 

Specs:

- 13700K

- 4090 FE

- H150i Elite LCD (only supported RGB device on system)

- iCUE 5.19.104

- Issue has been recently introduced

You need the QMLrender for the LCD.

Have the same issue.  I don't even have anything running on the LCD, just the default water temp and it drives one core of my CPU to 100%.  I just renamed it to QmlRenderer.exe.bak and then killed the process.  I would be nice to actually be able to use the LCD, but not when it eats and entire core.

I've updated to the latest driver and there appears to be an improvement.   It does appear to be taking anywhere from 0.5-2% CPU.  While this is certainly better than 10+%, I'm wondering what the CPU usage was prior to this issue coming up? Does anyone have any recollection or anyone on a previous version of the nvidia driver that can share?

Qmlrenderer is used by gpu to render the interface of applications on windows and on screens. My iCue showed more than 10% usage and temps of cpu on idle where around 50c. Now, I have 28c cpu temp and usage won't go over than 2-3%. My gpu usage while iCue is running won't go over 1%. Previous nvidia gpu drivers had high cpu usage but they fixed it with version 566.14
