Seeing that Ubuntu developers did nothing to locate this bug other than you guessing this might be a hardware issue – which was not an unreasonable guess, but I already proved wrong a long time ago – I finally took the time to locate this. I found which package causes the problem, located the bug in the source code, explained why it is buggy, and – even though I did not mention this – created for myself a one-line proof-of-concept patch (not suitable for mainstream commit), recompiled and installed the ibus package, and saw the bug indeed gone.
Please stop assuming it's a hardware or bios issue. It is absolutely clearly not.
Instead, please repeat the same steps I described in the original report on your default Ubuntu installations. I'm pretty sure you'll face the same behavior. (And in the unlikely case that you don't, you should clearly state this.) Thanks!
