Been using v3 for a couple days now and cannot find the View >Fullscreen mode. Was it removed? I work on a Cintiq Companion and screen space is very scarce and I can't figure out how to get rid of the taskbar, Top krita bar or document tab, even in Canvas mode.

I'm curious about this as well

It had to be removed from windows because it is bugged in qt5. The best alternative is to configure canvas-only mode in the settings.

I'm running Krita on Ubuntu 14.04 LTS. The fullscreen mode is still there. Have you tried the keyboard shortcut ?

Fullscreen = Ctrl + Shift + F

Canvas mode, too, looks fine to me.

I only disabled fullscreen on Windows, because that's where the Qt bug starts acting up: in full-screen mode, the menus are drawn behind the canvas if opengl is enabled. Not a bug in Krita, but in the underlying platform software.

Any chance of re-enabling it in future unofficial builds Boud? It's still usable with OpenGL off, which is how I have to use Krita on the SP4 anyway.

(c:

Making it conditional on whether opengl is on or not would complicate things a lot -- I don't think I want to do that. So it's contingent on the Qt people fixing their bugs... This is the bug: https://bugreports.qt.io/browse/QTBUG-41309

Fair enough, hopefully someone there gets on top of it. In the mean time I'll continue to hide the taskbar (which sometimes gets triggered by palm-touches) as a partial substitute.

On my sp3 (where weirdly enough I simply don't have trouble with the opengl canvas...) I actually place use krita with Windows 10 in tablet mode, which also removes the taskbar and things.

Hmm... how are you doing that? I still get a taskbar in tablet mode in Win 10.

weird, maybe that's a windows config option?

I 've found a workaround that solves half the problem: It is called borderless gaming, and it basically is a little program that can switch games and other applications to full screen mode. In other words, remove the titlebar and borders of the application window.

I am on Windows 10 and use a cintiq, so I put the taskbar to my main monitor, and with this I can use Krita as before
I just installed it and didn't notice any issues yet.

(Edit)
Well, there is a problem. Krita works great, but if borderless gaming is running when opening or closing the application, you get a freeze and sometimes a crash. I haven't lost anything as it seems that the crash happens after the application closes, but there you have it..

As I understand it, the original problem was that if I'm using OpenGl and in fullscreen, then I can't use popup-GUI or alt-tab.

To fix this, the fullscreen mode has been disabled.

I was wondering if this brute-force solution isn't worse than the problem it fixes? The lack of fullscreen eats up 10 % of my screen estate. And it's the vertical space too, which is sparse already.

It looks like "Canvas-Only Settings" has a Titlebar checkmark which also toggles fullscreen. Why not just let that be unchecked by default, and if I want to have fullscreen enabled, errors included, I can just add that checkmark.

You wouldn't have to cope with the user support requests -- and we get a lot of those these days. In any case, Michael Abrahams fixed this for 3.0.1, where we patch Qt to fix the issue.

Looking forward to that - thanks for the update!
