Thanks. It looks like the problem is indeed coming from the hardware, or the kernel:

Then only a few milliseconds later the right button was released. Much later (a tenth of a second) the left button was released. So yeah it looks like only the left button was a real click from a human :) It looks like a faulty mouse, sorry. Maybe the buttons get physically stuck together sometimes and can just be cleaned out somehow? ** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1850627 Title: Right click happens automatically, disturbs work Status in linux package in Ubuntu: Invalid Bug description: Since the last 3-4 days, the right click happens all by itself. Sometimes replacing the left click, while working in Inkscape or handling files on desktop for a fully updated 18.04. It is so annoying and good enough to destroy the work we are doing. I manually cleaned my mouse just in case hardware is causing the issue I tried using Cinnamon DE. There was no such issue in it. It would be great if there could be a fix. Thanks.
