Every now and again, if my phone has been on for a bit (like 5 hours or so), my landscape soft keyboard will just start duplicating letters and lagging like crazy. I thought, perhaps, this was due to extraneous apps being opened but it doesn't seem to ail the problem (using TasKiller); restarting the phone helps, within reason, but even then (sometimes) it still persists after a reset. Anyone else having this issue, or is there a solution I'm unaware of?
