Screen version 4.00.03 (FAU) 23-Oct-06

It seems that this only occurs on GDB 6.3. I've tried other versions 6.4, 6.6, 7.3.1 and they all appear to work correctly.

I can just use an upgraded version of gdb and it works, so you can probably close this bug.

I am unable to reproduce this problem. The screen versions I tried are git and ubuntu, and the gdb version is 7.3.1. What versions are you using?

When using gdb's TUI (Ctrl-X,A) and stepping through code, the screen does not update.

Steps to reproduce

1) Start screen session
2) Start gdb debugging session
3) Break somewhere in the middle of some code
4) Enable TUI (Ctrl-X then A)
5) Step to next instruction (n)
6) The Highlighted line (indicating where the PC is pointing to) will disappear and will not re-appear until you force gdb to update the screen again (arrow-up/down to force the screen to update)

I'm guessing it has to do with how gdb's TUI is highlighting the line that screen doesn't interpret correctly when that is the only update.
