Could you let us know of your system information? We've noticed a similar problem with some others before and are trying to figure it out.
I have a fairly decent pc running windows, which include:
AMD Ryzen 5 1400 Quad-Core Processor
NVIDEA GeForce GTX 1050
I don't think its about system specs though. If buttons have text on them which are larger than the button itself, it expands the clickable area and therefore can lead to you clicking the wrong buttons.
