Hey there,
I’ve known about this issue for a while, but I now realize it’s a bug from Roblox, not me.
Held-down modifier keys can get stuck “pressed” when the player window loses focus, and don’t get “released” when the window refocuses.
This causes issues when typing in input boxes. For example, if you type the letter a when Ctrl gets stuck, the entire message will erase except for the letter a. For me, this issue happens extremely frequently, and I’m not sure how I’m triggering it.
This LocalScript demonstrates the problem. It only works in a live game, not in Studio.
Repro steps:
Open the console in-game via F9
Click into the chat bar and type something
Hold Ctrl and click outside of the Roblox window while holding Ctrl (ie. click on your desktop)
Click back into the chat bar containing your text
Press a, the chat bar should clear as if you did Ctrl + a followed by a.
In the console “RELEASED” was never printed when you clicked back into the window, and is not printed until you press Ctrl a second time.
local UIS = game:GetService("UserInputService")
UIS.InputBegan:Connect(function(input)
if input.UserInputType == Enum.UserInputType.Keyboard then
print("PRESSED", input.KeyCode)
end
end)
UIS.InputEnded:Connect(function(input)
if input.UserInputType == Enum.UserInputType.Keyboard then
print("RELEASED", input.KeyCode)
end
end)
The ideal behavior would be for the InputEnded event to fire immediately after the window regains focus if appropriate, even if just for modifier keys.
I have a regular gaming keyboard w/ English keyboard settings on. I also run Windows 10 64-bit OS
This is extremely frustrating, because it makes it hard to connect with fans in-game and to socialize on others. Hope I can see a fix soon!
I’ve noticed this issue with A clearing my chat because of ctrl getting stuck somehow only recently, and I am also not sure how I’m triggering it.
However, a similar issue of alt getting stuck down such as when pressing alt + tab out of Roblox and then tabbing back in, has been plaguing me for a while. These may be related.
I’ve been playing a lot more social games (Trade Hangout) recently and I noticed that whenever I sometimes try to write something and press “a”, the chat clears. This happens also in different games at random. I have noticed this strange behavior like 2-3 weeks ago.
How to reproduce?
Join any game
Chat for a little (there’s no real estimate to how long does it take for the chat to break but I noticed that it’s usually around 10 minutes into the game, sometimes even sooner/later)
Try typing a word with “a” in it.
What should happen?
It should fully write the word.
What happens instead?
The message clears and leaves the “a” out.
And here’s a GIF that shows the described behavior.
I have a similar problem. My problem only happens to me when I edit the description of my game using the “Game Settings” button in Studio. Every time I press V, even when I’m not holding Ctrl, it pastes what I last copied and it’s very frustrating.
Maybe I should make a separate post about my problem, but I don’t know.
