I first encountered the issue while using a Logitech G502 Lightspeed mouse. Since, I have swapped to an Alienware AW610M. I’ve experienced the double inputs with both, while using both USB-wired. Plugging each in to experiment, both still occasionally double-input. I am using a laptop, the specs can be found in the attached video on the F3 menu if they’re needed. 

There is no custom mouse software installed, and I've only seen it present in 1.21. I'm almost certain this isn't a mouse issue and has something to do with the game. From what I've seen, many people encountering this issue are using laptops, which could be a common denominator.

Only when right-clicking. 

I have added a small video clip of the issue occurring with F3 open under attachments, I've tried to place the blocks as consistently as possible. This is something that happens almost constantly, and only when I'm placing blocks with individual clicks and not by holding the RMB down. I will also note since I opened the report I have reinstalled the game and am running into the same issue. I don't have the slightest idea how to reproduce this bug, but it happens most often in a singleplayer void-flatworld that has a large amount of active redstone within render distance. 

I'm not able to test if this is a multi-device issue, however, I've found many player testimonies online, and under MC-1887. If this is a Minecraft bug, I've been able to find posts about it dating back as far as 2011. I'll attempt to get a video of what I'm specifically encountering to help with identifying what's going on if that would help.

Will also add, this only happens with Minecraft. I've tested extensively outside the game to make sure I wasn't running into an issue with just my PC.
