Subject: Re: [edk2] simple_text_input_ex_ protocol typematic rate
Could you send part of the code where this is happening ?
It'll be easier to help on this case, since it seems to be a problem on the
application.
Thanks

I have a an efi app I boot to as bootx64.efi and it waits for keyboard input
(using either simple_text_input_protocol or simple_text_input_ex_ protocol)
for the most part (i.e., on most systems) it works fine, but recently i have
tried it on a newer toshiba laptop
and have issues indicatative of keyboard sensitivity, that is I receive
multiple of the same character if the key is not struck extremely staccato,
that is
i can not hold the key down at all else i get repeating characters.
oddly, this is not an issue if I boot to a shell, in that case the repeat rate
appears normal.
I have tried both the simple_text_input_ protocol and the simple_text_input_ex_
protocol with same results.
does anyone have any ideas what might be causing this behaviour in my app but
not in a shell?
thanks.
