It's really a minor bug, but since a while (in 2.8 it was already there), the Krita splash screen is black on startup, and get correctly displayed when the main window appear. Please see short video attached. I tried to identify the issue, and the best clue so far is some warnings when launching form a terminal : --- ################################### # Adding a tablet device: Wacom Cintiq 21UX stylus Device Type: "Stylus" # Axes limits data X: 0 87200 Y: 0 65600 Z: 0 0 Pressure: 0 2048 Rotation: -900 899 T.

I tried to disable color management in Gnome, to disable color management in Krita, to disable OpenGL, to delete my preference folder (~/.kde4/share/apps/krita) and kritarc file... And I only obtained once (deleting the preference folder and not the kritarc file) to see correctly the splash screen, but can't reproduce it anymore. I suspect a video driver bug, because the bug is present with the KDE environment. My video card : ATI Radeon HD4780 (R600) My config : Krita 2.9 Beta 3 Antergos distrib (Arch Linux based) Gnome 3.14 xf86-video-ati 1:7.5.0-2 (open source radeon drivers) lcms 1.19-5 and lcms2 2.6-1 xorg-server 1.17.1-1 mesa 10.4.4-1 Reproducible: Always

It's a gnome issue, I'm afraid. It works fine on windows, osx, kde and xfce, but with gnome3, the splash doesn't get painted. That's to say, not for you and me, but on Wolthera's laptop it paints!
Ok, so maybe for Gnome users with some video drivers ;) Tried with Gnome on Wayland, and Gnome Classique... it's the same ;p Do you think I should report a Gnome bug ?
I suspect it's a Qt bug, actually, scribus has the same issue.
So, here it is in the Qt bug tracker : https://bugreports.qt.io/browse/QTBUG-44557
Git commit 1aaba92f77b1148c6f7af81c90f7f121a3bae13d by Boudewijn Rempt. Committed on 20/02/2015 at 08:37. Pushed by rempt into branch 'calligra/2.9'. Gnome 3's window manager and Qt's splash screen don't work together. Scribus, Karbon, Krita -- every application with a Qt splash shows an empty rectangle until the main window is mapped. Is it a Qt bug? Is it a Gnome bug? I don't know, but it looks bad, so on Gnome, don't splash until the mainwindow is shown.

Thanks, I suppose it's the best in the interval !
