I have noticed no difference between the left and right shift, except in my own case I type slower with the right shift down, so that by itself causes it to happen less. If I try to hurry to match my left-side speed, it also stops working with lowercase characters. As I did some more testing, what seems to cause it is if you type a capital letter/symbol (something using Shift) and then release Shift before releasing the character. So if you press and hold Shift, press the key and then release Shift before releasing the key, it will get "stuck" (tested this using the on screen keyboard, and it would also get stuck with Shift showing as pressed down and then you can't type anything at all without adding another Shift_key). Doesn't happen all the time, but that seems to be what triggers it.
I feel like this is something that recently started as I've only noticed this issue for a few weeks or so.
