Created attachment 7075 Screenshot showing my #1 suspect Hello. Terminal Preferences windows always opens over 1400px wide even when I closed it much smaller before. This issue occurred after upgrading Xubuntu from 16.10 to 17.04, so I think it's related with switching GTK2 to GTK3. I think the information text on top of the 'Compatibility' tab may be responsible for this, because when I make the window smaller the text there doesn't have word-wrapping. So maybe this text frame forces the window to open wide to show whole information? Maybe it occurs only in my language translation? (Polish) I attached screenshot.
Hi Mariusz. Thanks for the report! You're right, this happens because of Polish translation - the long text string should contain a couple of new line chars ('\n') which would break it down into 3 shorter strings. I will try to contact the translator and ask him to fix this.
Thanks. I'm glad I could help somehow. My humble suggestion: Poniższe opcje mogą powodować nieprawidłowe działanie niektórych programów.\n Zostały one udostępnione tylko po to, aby umożliwić pracę z pewnymi programami\n i systemami operacyjnymi, które oczekują nieco innego zachowania terminala. PS: Seems like there's a double space between "udostępnione tylko" in the translation string, but I can be wrong.
Created attachment 7076 Proposed fix to the preferences dialog layout The patch (first commit) limits the label width to max 80 characters and fixes this bug. The second commit removes manual line breaks from the untranslated label (optional).
String fixed on transifex.
Andrzej, I've merged your 1st patch, thanks!
