## Revision as of 18:53, 8 February 2010

IMPORTANT NOTE: The 2.53MP is a leaked beta. Please do not distribute it to people by calculator until TI makes the official release, slated for February 15. Use at your own risk.

# Known Bugs

- Programs using the homescreen may be very broken. Users should disable Math Print before running them, and programs should clear the screen first thing.
- Programs that encounter an error on the graphscreen may end up with the graphscreen contents in the homescreen buffer
- In Omnicalc, parenthesis assistant does not work properly. (Display error)
- In Omnicalc's entries menu: Using the entries menu without MP symbols has some display issues, and when selecting an entry, it crashes.
- In Omnicalc's entries menu: With mathprint symbols in the entries log, there are serious display issues accompanied with a dramatic crash.
- Omnicalc's partial line clearing (always enabled) crashes or glitches when you try to use it in MP.
- Calcutil will not run at all correctly and will crash your calculator when you turn it off and back on.
- ld a,1 \ ld (appInfo+2),a \ bcall($50CB) no longer unlocks the flash ROM.

# Known Performance Issues

- Disp and Output may be up to 4x slower than on previous OS version (see TI-84+ OS v2.53 Leaked)
