All left mouse clicks extremely delayed (feels like maybe 100ms)

HionV · 2026-05-23 07:21:42

I have tried to look for answers or solutions online but it's hard to find anything that even documents this problem. This only happens to me on XFCE, doesn't happen on Plasma, GNOME, Hyprland or COSMIC.

The issue in question is that whenever I click left mouse button, the input is severely delayed by what I'd guess is about 100ms. This is very noticable when playing games, and ruins counter-strike 2. Is there something I am missing? I tried nearly all the toggles in 'window manager', 'accessibility' and 'window manager tweaks', I can't get rid of this horrid input delay. It only happens with mouse1, when I use rivalcfg to rebind mouse1 to the side buttons and bind mouse4 on my left mouse button, and then in game switch to mouse4 for shooting, the problem does not happen, and this noticeable delay still happens on mouse1 inputs which are then on my side button, ruling out this being a hardware problem.

Does anyone know what might cause this, or how to fix it?

Thanks!

What video card and driver do you have?

To confirm, does it help if you disable compositing? Window Manager Tweaks > Compositor tab > uncheck "Enable Display Compositing"

Thanks for the reply!

Disabling compositing does not help as it is something I already do to get better latency when gaming. It's specifically just left clicks being delayed (maybe right clicks too, didn't test too extensively), everything else appears low latency.

Currently running an Intel Arc B580, but from what I remember I had the same issue back when I was still running an Nvidia GTX 1070.

I tried using the side buttons on my mouse as a workaround but that's not the most ergonomical solution.

This issue is quite a shame, as besides this problem, XFCE from all the Desktop Environments I tried seems to otherwise be the most performant for gaming workloads, as on Wayland compositors it seems with my hardware I cannot get the tearing protocol to work causing forced VSync which also introduces input latency, so while this issue persists I'm best off running KDE on x11 I guess, as I don't run into this issue there, as well as being able to force disable compositing using window rules.

I still think it's odd though, like something within xfce (or the input libraries and how they're configured) just seems to eat mouse clicks and buffer them for a small amount of time. Not enough time where I think most people would notice, but when I play cs2, it's enough as to where I try to shoot someone with a sniper and then switch to my knife or pistol, the shot never fires before switching.

Can you try running xfsettingsd in debug mode?

xfsettingsd --replace --no-daemon --debug

Try to get the issue to occur, then look to see if anything is posted in the output.

No output sadly

[andreas@drivebystation-nix:~]$ xfsettingsd --replace --no-daemon --debug

edit:
also did some testing and right mouse button clicks are also confirmed delayed similarly.

Try this instead:

pkill xfsettingsd
XFSETTINGSD_DEBUG=1 xfsettingsd --replace --no-daemon

Lets see if xfsettingsd is picking up some sort of delay.
