So, heres my issue. Whenever I play CS-GO (Counter Strike Global Offensive), at random times it will just ignore when I press my touchpad buttons for a fire input, or it will be a heavily delayed input. It starts off only occasionally, the longer I play the more and more it does it. It also never happens if I use a keyboard key as my fire input, only the touchpad buttons.

This does not happen in any other program or game. Ive tried getting it to replicate in Edge, CS: Source, several visual novels, Minecraft (both 1.12.2 and 1.8.9, Optifine and Labymod included), Steam, Discord, Chrome, CS 1.6, Half Life 2, and other programs I can't remember at the moment.

In addition, ive also tried to re-verify the game files multiple times, re-installed the game, uninstalled and re-installed my touchpad driver, and even going so far as uninstalling my antivirus to see if that was the cause.

Is this a hardware/chipset specific issue or glitch, or should I just buy a mouse to fix it? Its becoming very problematic in matches and games.
