xfwm4 stuck at low frame rate

Hello. First time user of XFCE. I've been using KDE/Plasma for many years, and recently decided to try XFCE (due to some problems with KDE.)

I'm using a high refresh rate monitor, and for the desktop I always use 120Hz. After installing XFCE and running it, I noticed that the compositor is stuck at 60FPS. I'm used to KWin and MS Windows @ 120Hz (I'm dual booting) for so long now, that XFCE seems very blurry and slightly stuttery and laggy/unresponsive. Turning off compositing in xfwm4-tweaks-settings fixes the issue, but I'd like to keep compositing enabled. It just looks better, even if just for the shadows.

In KWin, I could configure the frame rate the compositor uses (through the "MaxFPS" variable.) Is there an equivalent setting for xfwm4?

Re: xfwm4 stuck at low frame rate

Did you try with / without the "sync to vertical blank' setting in tweak settings? Also can you select the refresh rate in display settings?

Yes. Doesn't help.

It's  set to 120Hz.

If you use a nvidia graphics card did you try to enable the composition pipeline? hjMqVLr.png

Does not have an effect on frame rate. Still stuck at 60FPS.

Re: xfwm4 stuck at low frame rate

The mode is correct and the monitor is operating at 120Hz.

The issue is not the refresh rate. It's the frame rate at which the xfwm4 compositor renders frames at.

I suppose I should report this as a bug on the bugtracker then.
