Hi, recently I have upgraded my Yocto image and SDK from Morty to Pyro. (I'm not ready to upgrade to Rocko since meta-boundary layer is not prepared yet. My SoC is Boundary Devices Nitrogen6x_MAX QP). After the upgrade and rebuilt with the new SDK my software has two problems: 1) moving with elements on the touch screen (eg. QSlider) is not continuous and has got a visible delay (about 1 sec) 2) imxeglvivsink is able to view the gstreamer video correctly only within the first start of the application (after power on). When I kill the application and try to run it for the second time, imxeglvivsink shows only a black screen. I have the same problem with a basic pipeline: export DISPLAY=:0.0 && gst-launch-1.0 videotestsrc ! imxg2dvideotransform ! imxeglvivsink On the other hand, the following pipeline works OK. gst-launch-1.0 videotestsrc ! imxg2dvideotransform ! imxg2dvideosink What should I change in my Qt or imx configuration after the upgrade to Pyro? The only change in the recipe list between Morty and Pyro is that in Pyro I have removed OpenCV recipe. But I don't use OpenCV explicitly in my software anyway. Furthermore, I use X11 and matchbox-window-manager. Best regards, Vaclav Mach
