A few years ago, I believe I came across a post here somewhere that explained (and even showed with a screenshot) that the Update Manager dialog which notifies the user of a new distribution release was way oversized. Like, the dialog was way too tall, so tall that the dialog's buttons along the bottom of the dialog were pushed off the screen.
This issue recently returned to my attention when I was writing my own dialog box code, and encountered the same problem:
I figured out what was wrong -- the dialog, by default, is resizable, and due to a limitation of GTK, the dialog needs to allocate enough physical space for the case in which the user resizes the dialog to its minimum width, and therefore the text within the dialog will be of maximum height (due to word wrapping). I figured out that by setting the dialog to be non-resizable (which is the traditional, pre-GTK+-3 behaviour of dialogs), the dialog shows up at its expected size, without pushing the buttons offscreen:
I would be happy to fix the issue in the Update Manager, but the problem is I can't find any real, existing documentation that this problem even exists (though I swear I've seen it in the past!).
So my question is: Does anybody know where this issue has been documented before? And most importantly, can anybody confirm that this issue still exists in the latest release(s) of Ubuntu (MATE) -- preferentially with a screenshot as an example?
Thanks in advance to anybody who can help me.
