Hi! I hope everyone reading is doing well. I am working on developing a reinforcement learning agent that involves sending scan codes to a window, which I've been doing by sending virtual scan codes with CGEventCreateKeyboardEvent per the docs. There is no event source when I send the keyboard events. However, when many keyboard events are happening (with the keys 'q', 'w', 'e', 'r', 'f', 'd', 's', space, arrow keys) in quick succession (<250ms), the enable dictation popup or the function button emojis popup appear for seemingly no reason. I have verified that I am using the correct scan codes for these keypresses, so I am wondering what else could cause this to happen. It is as if I am choosing to press f5 or fn. It does not happen when 'a' is the only button being pressed in quick succession. One thing that I have not been able to easily find is the scan code inputs for dictation nor the function button. do these scan codes overlap somehow? Thank you all for the help! Hunter

During editing in Pages (or Word) I am getting these glitches (see attachment). Started after the last update to Mac OS 26.3 (beta) Also removed 2 recent instalments (Blackhole audio driver and kDrive/Infomaniak, but trouble is still there. 27" iMac 2020 (Intel) i7 3,8 Ghz AMD Radeon Pro 5500 XT 8 GB 24 GB RAM macOS Tahoe 26.3 (=beta) Tried restart in safe mode, checked fonts. Talked to aissistent to get a solution, but no ...) Thx for any advice, Pieter (not a developer so please kee pit simple 🙏🏻)
