If your shell command line looks like: sh-3.1# abcd Then insert another 'b' in front of the existing 'b'. The 'c' will become corrupted. The actual characters don't matter, except that the inserted character must be the same as the existing one. It happens in all even columns, so if your prompt is different, just try it at a different even position. It happens in frame buffer depths 2, 4, and 8. In monochrome mode the corruption is different. In 16 bpp, when it uses the cfb code, there's no corruption, so the bug must be in the Atari-specific code. I could not reproduce it in vi, only in bash. Tested on ARAnyM only.
FTR, this was "fixed" in commit 81732c3b2fede049 ("tty vt: Fix line garbage in virtual console on command line edition") in v3.7, followed by a few fixes for the regressions introduced by this fix.
