so I have this issue for quite a while now and no update seemed to help so far.
After a fresh install of Manjaro KDE Plasma, my Keyboard sometimes prints double letters and sometimes ignores the keystroke. But only the letter “o”! It´s common, but unfrequently and there´s nothing in the Kernel-Log.
My Keyboard is a Logitech G910 Orion Spectrum and works absolutley fine apart from this issue.
Whats even more strange is, that this apparently does´t happen in WINE Programs, because it never occured there (though I haven´t typed enough to 100%ly confirm this).
(I will not correct the mistakes from here on, to show an “example”)
I´m on Manjaro Testing Branch with Kernel 5.17.1, but it alsoo occurs in all versioons of Kernel 5.16 and in the versioons of Kernel 5.15 I´ve had installed (currently 5.15.32).
As I haven´t found anything comparable online yet, I´m asking here now if anyone has had such an issue befre.
It´s a mechanical keyboard and there´s no dirt whatsoever under the keycap.
I also can feel that the switch is triggered, when either no letter is typed, or doubled. There´s absolutely no difference in feel between correct typing and when the bug appears.
Since it’s mechanical, if you can solder and find a suitable replacement, then you should be able to fix it.
EDIT: They seem to be Romer G tactile switches. I found some on amazon uk, looks like both linear and tactile, but I’m not sure which are which. Presumably you should be able to get them elsewhere too.
