[unity8] child windows don't have a minimum size, you can resize the windows to ludicrous sizes

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 1511604, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

Oops, sorry, this is only a duplicate of bug 1511604 if it's using Xmir. It looks like the above apps will be native GTK instead.

Sorry again, this is also not a GTK bug. The windows you mention correctly implement resize constraints and I can confirm this on Unity8 17.04.

So I can't reproduce the bug...

Is Xmir running on your system?

all the apps are running native here, no Xmir

I guess the bug is really that those child dialogs shouldn't be resizable in the first place, like in Unity 7, right?

Just tried with calculator. It does set seem to be setting a minimum and a maximum width with the same value since I cannot resize it horizontally.

And vertically, I can only enlarge it but not shrink beyond its original size.

yep the main calculator app seems to resize as it should, i think. the problem is with child windows, "About", "Preferences" etc, they don't seem to have at least a minimum size, you can make them as small as you like

I meant the child windows of those apps.
