I haven’t seen any posts about it, so I don’t know if it’s a common issue or not, but the chat will occasionally push everything up, as if there were 10 blank messages pushed to the server. If I scroll up, I’ll find the old chat, but there’s a lot of blank rows in the chatbox, making it look empty. When people start chatting again it behaves normally. However, another interesting thing is that today the chat was cleared completely (no chat messages when I scrolled up), and when people chatted I could see the bubble chat, but nothing was added to the chat box. Unfortunately, I didn’t check the error console, but thinking back on it, the most likely cause was an error. I’ve only had this happen when I try to resize the window / switch windows while ROBLOX isn’t maximized, but I can’t seem to get a repro. I use Windows 7 64-bit on both computers that this has happened on, and I hadn’t modified any of the non-studio settings. If anyone has any concrete repro steps, that would be awesome – otherwise, I’ll post some if I manage to find a specific way to do this.
