Yeah they will be if you use a lot of those old style toolbars-forms-and-dialogs apps. For other apps I don't see much interest in Qt Widgets.

Wtf. We really live in different worlds. Most programs you use in your desktop are not "toolbars-forms-dialogs-and-buttons" ? What exactly do you use ? Braille interface ?

  Web browsers? Programs based around images/video? LibreOffice? Krita? Blender? Most "productivity" apps I see are based around a canvas or around images in some way. If they can hardware accelerate that, they will.

    All of these are "toolbars-forms-dialogs-and-buttons". Something like this https://github.com/KDE/kongress/blob/master/screenshots/combined.png https://github.com/KDE/kongress/blob/master/screenshots/comb... would perhaps not be "toolbars-forms-dialogs-and-buttons" , but that is hardly recognizable as an application you find on your desktop PC.

      Except they aren't really, the main widget in all of those is already an OpenGL accelerated canvas... If your application is primarily a form or a dialog then yeah, but everything else that has images or video or custom drawing is going to want hardware acceleration. Maybe you spend a lot of time filling out forms or in text editors or writing emails? But I think even those text-based apps will want to be hardware accelerated eventually too, just look at the number of GPU rendered terminal emulators that are popping up.

  I can't say that's been my experience!

    I've just checked my desktop and (besides a ton of terminals), I have : - Zim (GTK widgets note taking app): https://zim-wiki.org/ https://zim-wiki.org/ - Strawberry (Qt widgets music player): https://www.strawberrymusicplayer.org/ https://www.strawberrymusicplayer.org/ - QtCreator (Qt widgets IDE) - KTimeTracker (Qt widgets time tracker) - Telegram (Qt widgets, even if it does not look like it ;p) - Firefox (its own thing, hardware-accelerated) - VSCode (electron, hardware-accelerated) My document-writing software is TeXStudio, also in Qt widgets. The main software I work on, https://ossia.io https://ossia.io is too (the canvas can be rendered with Qt's GL painter but this leads to better performance only on 4K+ resolutions, on 2K Qt's software renderer is faster and has less latency in all the systems I could try, and has a way lower "idle" energy consumption as it does not particularly wake the GPU). Other than that, software that I use occasionnally are all widgets-based and don't do GPU rendering (AFAIK): LMMS, QLC+... Anecdotally, I tried every GPU accelerated terminal I could find and none felt as good as my trusty old urxvt
