When typing fast on UHK, characters stop being typed consistently after est 37-100 characters

Thanks mlac and kareltucek. I’ll try these solutions today to see if they work.

This is unrelated to the thread’s issue, but since I have your attention(s); my right half’s bezel thumb button’s switch is no longer functioning properly. It does not click when I push down, but does click upon depressing. The left bezel button works as expected. I don’t see any replacement parts for this, and its admittedly made me stop using that button.

I’m also experiencing key repeat issues that this user is is reporting with their M key, but mine is with the enter key (M button produces two keypresses instead of one, 30% of the time -- is there a software fix? - #3 by kareltucek).

What are the odds that I got a lemon? Or is this par for the course? I’m down (albeit a little nervous) for self repair, but curious if I’m an outlier in that respect.

Thanks for your time, I’ll report back ASAP.
