--- Comment #13 from Armin K <kre...@email.com> --- (In reply to comment #5) > > And without DRI_PRIME=1 everything works everywhere, with or without > > compositing, windowed or fullscreen. > > I would imagine this is because you're not offloading anything at that point > and running it on the IGP. > > >I don't recall having any problems under KWin or Xfwm4. > > This is because KWin defaults to Xrender, and Xfwm4 is *only* Xrender. > xcompmgr works fine, too, as do the default settings on Compton. > I've used KWin OGL3.1 backend. For Xfwm4, if you don't enable Display Compositing in Settings -> Window Manager Tweaks -> Compositor, you'll get black screen too. > If you try this on: > > * GNOME3 > * Cinnamon > * Compton with --backend glx > > You will get a black screen. > > However, if the screen is *not* full screen, you can resize the screen and > the image will appear (such as with glxgears or glxspheres). > > Unfortunately, in screens that are "full screen windowed", as are many Wine > games, it still shows up black and there's no way to resize the screen in > order to make the image show up. In any case, that's not really an > acceptable workaround because it just shows that there's something wrong > with PRIME offloading that causes this odd behavior on GLX-based compositors. -- You are receiving this mail because: You are the assignee for the bug.
