Hello
Using my mouse on my external monitor has become extremely laggy but in only very specific conditions and I cant figure out why. It lags unless:
- I’m using my laptop’s mouse-pad
- I’m playing a game where my mouse is locked
- My cursor is on the internal monitor on my laptop
By laggy I mean the mouse is very snappy and unresponsive, and also my current task on the monitor freezes for a moment or two. This doesn’t effect the internal monitor of my laptop.
I have tried using different USB ports, using a different mouse and there is no effect. Ive tried switching the HDMI cable and nothing changes either. Ive also looked online and there’s nothing very similar to this specific issue as far as I can see, however I did check my CPU usage and it seems that my mouse on my external monitor uses only one core and causes it to peak. In fact any input from my mouse to my monitor seems to do this, including using right or left click.
I tried switching to my NVIDIA GPU, and while it worked initially the lag got worse and worse over time until it got into the same condition. I also noticed this happened over the day in general, where the more i would use my mouse (outside of the previous conditions) the worse the lag would get.
This only started after I updated recently. Might be a coincidence but I figured it was worth mentioning.
Edit: Using my mousepad is still peaking my CPU, but not causing as much lag. Its still someone noticeable though
