5724 | Jason Rumney earlier refused to call change_frame_size right here |
5725 | with the following argument: | |
5726 | ||
5727 | The following mirrors what is done in xterm.c. It appears to be for | |
5728 | informing lisp of the new size immediately, while the actual resize | |
5729 | will happen asynchronously. But on Windows, the menu bar | |
5730 | automatically wraps when the frame is too narrow to contain it, and | |
5731 | that causes any calculations made here to come out wrong. The end | |
5732 | is some nasty buggy behavior, including the potential loss of the | |
5733 | minibuffer. | |
f8d1a163 JR |
5734 | |
5735 | Disabling this code is either not sufficient to fix the problems | |
5736 | completely, or it causes fresh problems, but at least it removes | |
5737 | the most problematic symptom of the minibuffer becoming unusable. | |

cfd5e825 MR |
5739 | However, as the discussion about how to handle frame size |
5740 | parameters on Windows (Bug#1348, Bug#16028) shows, that cure seems | |
5741 | worse than the disease. In particular, menu bar wrapping looks | |
5742 | like a non-issue - maybe so because Windows eventually gets back to | |
5743 | us with the correct client rectangle anyway. But we have to avoid | |
5744 | calling change_frame_size with a delta of less than one canoncial | |
5745 | character size when frame_resize_pixelwise is nil, as explained in | |
