Isn't this linked to / same as #1449858?

#1449858 is about entry widgets. The comments there indicate the same problem in text widgets, but I am not aware that anybody has filed a bug report for text widgets. THIS bug report shows the same problem for text in a canvas - yet a different basic mechanism to put text on a screen that is apparently suffering from the same problem.

This means that there is apparently no way to write an application in Tcl that can display a random text file with long lines. That strikes me as severe.
