Documentation

Maximum number of redisplay ticks before aborting redisplay of a window.

This enables aborting the display of a window if the amount of low-level redisplay operations exceeds the value of this variable. When display of a window is aborted due to this reason, the buffer shown in that window will not have its windows redisplayed until the buffer is modified or until you type C-l (recenter-top-bottom) with one of its windows selected. You can also decide to kill the buffer and visit it in some other way, like under so-long-mode or literally.

The default value is zero, which disables this feature. The recommended non-zero value is between 100000 and 1000000, depending on your patience and the speed of your system.

Probably introduced at or before Emacs version 29.1.
