   I'm using Linux Fedora 43, I have the same issue.
   Based on @halilang70-png suggestion, In production app, I changed input to textarea (via dev tools) and the delay was gone but the @mention styling was also gone as expected.

   However, There's no laggy typing when I run the desktop app in my chrome browser (from source code).

   They say it's the git, If a large change was made by ai agent ,the open code trying to scan the git DB so it become laggy,but how can I use an ai code agent without git, maybe this a asynch problem

   I built an RPM file on my linux, then used this RPM to reinstall opencode desktop app.
   Now it's not laggy any longer when I use opencode on the same project which was laggy before.

   Give it a try. Solve the issue first, then we'll find the reason :-)

   @halilang70-png I added this option to app settings so that I can disable electron hardware acceleration and the input delay decreased significantly.
   I think there might b some issues with electron hardware acceleration on some gpus too.
