Comment 0 for bug 1756877

I am on an Dell xps 9530 laptop and I had recently cleaned installed 17.10. A few days back I decided to updated to 18.04 to check it out and report some bugs. The most annoying bug so far is the insane amount of input latency this update has brought with it to a degree that it makes it impossible to be productive. The issue is observable when using either the mouse or the keyboard. The mouse does not move immediately but it needs a second or two to register and start moving and even then at some point it freezes for half a second at some random point and then moves again. Also if I have two applications side by side and I try an move focus from one to the next at around the edges of each window the mouse freezes for a second and then moves. The keyboard freezes if it hasn't been used for a while and on the first keystroke will take a second to register and for a bonus you get the first keystorke repeated for around 15-30 times. So if you are trying to write "and" will become "aaaaaaaaaaaaaaand" or pressing "ctrl + T" in the browser will open not one but 20 tabs!

I am reporting it here cause I am not sure what is causing all this latency (it could be libinput or something else entirely) but please try and fix this as soon as possible!!
