Created attachment 113241 [details] Screenshot of Plasma 2 Hi there, I don't know where to start because I just migrated to Plasma 2 and got this black texture (see attachment). Everything is fine using Qt4, so I suppose this could be a Qt issue? But then I used vesa as Xorg driver and the texture is painted correctly. The same black texture is used in SDDM too, which is also a Qt5 application. Any idea on where to start? NVIDIA FX 5500, Xorg 1.16.3, mesa 10.4.4, nouveau 1.0.11, Qt 5.4.0
(In reply to Andrea Scarpino from comment #0) > NVIDIA FX 5500, Xorg 1.16.3, mesa 10.4.4, nouveau 1.0.11, Qt 5.4.0 Still the same with Xorg 1.17.1, mesa 10.4.5, Qt 5.4.1
The thing immediately coming to mind was the workaround I added for dealing with mismatching color/depth render targets. The "fix" was to just not render to depth at all, but that may mess up other things of course. (Not the least of which is that the depth texture will remain untouched.) To start, you should get an apitrace (https://github.com/apitrace/apitrace) of the failing application. This should help determine what's going on. Make a debug mesa build and see if the driver outputs any "aaaah, i don't know how to handle this" type messages.
