Did you observed it with evemu or with libinput? Please use former as it connects directly to input device and gives raw data. > Some devices *might* support simultaneous presses of multiple media keys,= but I think in that case, we would just lose the extra key presses. I recently implemented evdev support for consumer page for bluetooth keyboa= rds (not publicly available yet) and found out that my bt-keyboard loses *relea= se* events on simultaneous presses as it is unable to report "which key has been depressed" at HID-protocol level. It is capable only to say that "last/all = key has been depressed" so my driver has to generate release event at next interrupt at his own. I do not see how your patch does such "autorelease". Maybe ukbd does this automagically? I should look deeper in its internals. Unfortunately I cant do hardware testing now --=20 You are receiving this mail because: You are the assignee for the bug.=
