Unity 5.3 released, hello modern OpenGL system for Linux gaming

By - | Views: 20,428
Unity 5.3 has been on my radar for one single reason, they finally have a modern OpenGL system! I really hope developers upgrade to it.

QuoteWith Unity 5.3, we’re shipping a number of new features which raise the bar for rendering quality and deliver improvements to rendering efficiency.

For starters, there’s a brand new OpenGL 4.x core, which will replace our legacy OpenGL 2.1 core. This allows you to take advantage of the very latest OpenGL features on Windows, OS X and Linux, whilst also being able to scale to older versions of OpenGL, depending on the user’s OpenGL driver support. Note that in 5.3, Unity will default to the new OpenGL core, but you can switch to legacy OpenGL 2.1 manually to maintain previous behavior. Our current aim is to remove the legacy OpenGL core in Unity 5.4.

See the full announcement here.

I would urge developers to update, as the Linux version should perform better with the new OpenGL system in. I am also pleased to see them aiming to remove the legacy system for the next major update, no point keeping it around. Article taken from

From what I've seen, this has been a Gtk theme issue for the people who are experiencing it. You may have better luck if you try a different/standard Gtk2 theme.

Thanks, I finally managed to get a file dialog! X)

I installed kde-config-gtk-style to access gtk configuration with KDE means.
It was set (defaulted to?) mimic KDE style.
I had to change the theme, away from "oxygen-gtk" to e. g. "Adwaita", as well as the icon set, away from "Oxygen" to e. g. "Human" or "GNOME". None of the changes helped on its own, but both together did.

I've added the information to my crash report as well (

Thanks for your help!
(Did you know that "tack" is the Swedish word for "thanks"? ;) )
