Are you sure that it's not simply a difference in hysterisis? I would expect most software using those values to ignore "close to center" jitters. You might also want to make your script use the actual min/max values for those analogue sticks, I don't think they're actually between -32767 and 32767 as you use in the script (although I don't have a joypad to verify this right now). > $ uname -r > 4.19.0-1.fc30.x86_64 You say it's a regression, but in which kernel version was this working?
