Scrolling in browser (Chromium, Firefox) affected

[dodalovic]

Hi, I really like the product, first of all.

One thing I spotted is that when libinput-gestures is active, then scrolling in browsers I have installed is affected. Pretty much, it's not smooth. I have a touch screen and using the latest Pop OS.

Please, let me know if I can better describe the issue.

Thanks!

Yes, please read the first paragraph of the trouble-shooting section and provide the essential info requested there.

I haven't done any config, I was just doing minimal install. When I was using two fingers up/down (for page scrolling) in debug mode, this wasn't printed out. Just three fingers were printed out in the output.

Nobody else have ever commented that this small utility imposes any noticeable effect on their system. Try scrolling in your browser with this utility disabled/enabled (libinput-gestures-setup stop|start) with htop running in a terminal and see if you can see it affecting the CPU. I tried on my old laptop and I can't see any difference. Make sure you are have the same browser tabs open etc, and keep everything else constant. Please also paste the output of lscpu here.

I believe your analysis is correct at the very end, and very likely this smooth scrolling issue might be related to something else (trackpad or my 4k screen, or whatever else). Sorry for bothering :(
