Ever since 1.17 came out in June 8th I’ve had this weird issue on keyboard and mouse only on Bedrock edition. Every time I open my inventory my mouse teleports all the way up or all the way down so my screen teleports up or down every time I open my inventory. I’ve told my friends that play on Keyboard & Mouse and they also have this issue. I’ve found a troubleshoot however, If you go to settings, Video, and turn screen animations (ON) the glitch will temporarily disappear but it will come back after 5 - 10 minutes. But it always happens with Screen animations (OFF) This bug applies to Servers as well.
