GNOME Bugzilla – Bug 170657
GtkLabels are vibrating on resize when the text is ellipsised and the text-adjustment is not 0.0

1. Create a GtkLabel with long text and set the ellipsising mode (e.g. to ellisize at the end) 2. Adjust the text to the middle (0.5) 3. Make the window so small that the text needs to be ellipsized 4. Play around resizing the window and see that the letters are jumping partially several pixels wide == I would recommend to automatically set the text adjustment to 0.0 until the text doesn't need to be ellipsized.
Created attachment 79402 [details] Testcase Compile with gcc -o testvibration testvibration.c `pkg-config --cflags --libs gtk+-2.0`. The label will jump a few pixels back and forth when the window is resized.
I'll rather fix this in Pango. All we need is to ensure that an ellipsized line has its goal width. The extra space should probably go between the ellipsis and surrounding text. Makes sense?
Might be a bit nicer to distribute it across the whitespace in the line, but for now just putting it there should be fine.
You probably can get it distribute by turning justify on. Probably doesn't work now. Anyway, it's a lot easier to fix this now that justification works.
