FWIW, I *cannot* reproduce that in KOReader.

Whether it be the Elipsa's panel or the Sage's buttons, I can only ever miss *a single* gesture, and only if that event is a wakeup source (that's generally a single press down -> up for buttons, and a single contact down -> up for the panel, although it's more complicated there because it also suffers from spurious 0-pressure events issues). Duplicating the offending gesture works immediately (and the kernel is woken up by the missed input).

(For those missed inputs, I've also *never* seen weirder crap like only seeing an up without a down, or vice-versa; or even parts of it being interleaved with a later input frame; something which could arguably confuse the hell out of a finger tracking algo. AFAICT, the entire gesture gets sent into the void and never hits userland.).

I've never seen the "stuck" issue either on my device, but KOReader's KEY_REPEAT handling is fairly basic, so there may be a bit of software tomfoolery there, even if I've never actually seen spurious REPEAT events myself during my extended time poring over input frames on those devices .
