"Edit Brush Settings" doesn't open if pressing F5 nor by clicking on icon on toolbar. It stays closed. Reproducible: Always Steps to Reproduce: 1. Click on "Edit Brush Settings" 2. Press F5 3. Actual Results: Brush editor stays closed. Expected Results: Brush editor should open for brush adjustments. Appimage 3.0.1 used, brush editor doesn't open . The PPA 2.9 version does work correct, brush editor opens.
Which distro/desktop enviroment are you on? I know unity doesn't allow me to select anything on the pop-ups until I open and close them a few times.
Sounds like a very confused window manager to me.
I use 'Gnome 3' 3.18.1.2-1ubuntu1.16.04.2 Linux 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:01:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux. I noticed that all works fine with Unity and Enlightenment 0.21 On Gnome 3 all works but the mentioned "Edit Brush Settings" and F5. Pity that Gnome 3 fails on me here as it is far out my favourite.
I'm sorry, but there's nothing we can do here. We don't code the popup functionality ourselves, it's part of Qt. If with other window managers it works, it must be a bug in the window manager. Even so, when I try Gnome 3 myself on OpenSUSE, the problem does not occur.
I have managed to get "snap" Krita 3.0.1 running on Gnome 3 on Ubuntu. With the "snap" Krita version I have no problems with "Edit Brush Settings" or F5. So with "Appimage" "Edit Brush Settings" doesn't work, with "snap" version 3.0.1 (git 7c6cf9c) all works fine. This is on Gnome 3. "just for your information" Jan
