Question Super weird keyboard bug ?

[audio369]

This is amongst the weirdest issues I've faced on this PC so far. For some weird reason the keyboard is acting finicky and it seems like it's not responding correctly. "Seems" being the key word, everything I write registers on the screen, but as I'm typing them it almost seems as if I'm deleting letters when I type. This is super hard to explain so I just recorded a vid of it happening. Google Drive link. (sorry about dirty screen) I am just spamming keyboard letters in this video and I didn't press delete at any point. It happens sporadically and unpredictably. For example right now it hasn't been happening for a while but when I recorded that video it was happening for like 30 secs straight.

My system is brand new:
i5-13600k
ASRock Z790 Steel Legend
g.skill ripjaws s5 6kmhz 30cl
the only thing that's recycled is AMD RX 6600. I don't think this is a graphical issue however.

Another bug that accompanies this one is sometimes when I open a new tab on Brave (chromium) it almost like flashes or flickers before it goes back to normal. I don't have any video of this as this is even rarer than the keyboard one, but usually when it happens it's not long after the keyboard starts glitching. Likewise for example when I'm typing this, sometimes when I put the mouse over the box where I'm typing it disappears until I take it outside of the box and put it back in, and then it acts like normal. What could be causing this? This is also a fresh install of Windows.

Only things I've installed so far are: Brave browser, Steam, FL Studio, Drivers through ASRock Auto Driver downloader. I haven't manually downloaded CPU or GPU drivers, when I scan them in Device Manger it says everything is up to date. I don't want to mess [Moderator deleted profanity - remember that this is a family friendly forum.] around w/ drivers too much cause when I manually downloaded everything from ASRock, intel and AMD I was having unbearable DPC latency issues which I have finally been able to fix with a fresh reinstall, but now this, smaller but still annoying glitch is occuring. Any ideas?

Unable to view the Goggle Drive link???

Try another known working keyboard on your system.

Try the problem keyboard on another known working system.

Determine if the problem follows the keyboard or stays with the system.

Try running "dism" and "sfc /scannow" to fix corrupted files.

If the problems continue take a look in Reliability History/Monitor and Event Viewer for error codes, warnings, or even informational events that may have been captured just before or at the time of the glitching.

Fixed the google drive link, please take a look. I'm scanning the system atm.

Try a clean boot and see if it changes anything - make sure to read instructions and make sure NOT to disable any microsoft services or windows won't load right - https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows
It doesn’t delete anything, it just stops non Microsoft programs running with start. Easy to reverse.
if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.

You might also open the registry and navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318} (you might find it easier to just search for the {4d36e96b-e325-11ce-bfc1-08002be10318} GUID). In there look for the UpperFilters entry, if you see anything other than kbdclass then some third-party app has added a keyboard filter driver and that's probably what's causing this.

Take a backup of this entire key and then remove all filter drivers except kbdclass. You will lose the functionality provided by the removed drivers but the typing issue should be gone. You can then investigate what's installing keyboard filter drivers....
