    Description

      The problem is said (and probably indeed is) to be only reproducible on Nvidia Tegra TX2. I don't have that specific hardware, but I can confirm that the problem does not reproduce on Apalis i.MX6. Anyway, according to original reproducer, the steps to reproduce the issue are:
      1. Build and deploy modified minimal-cpp compositor example to TX2 (modified compositor attached as reproducer)
      2. Launch another application (any Qt app should be fine) with -platform wayland (may need some other env vars like WAYLAND_DISPLAY if it is Qt6) so that it is shown inside compositor
      3. Press F9. The modified compositor implements

          if(nativeScanCode == 75)
          {
              for(auto v : m_views)
              {
                  v->m_iviSurface->sendConfigure({300,200});
              }
          }
      

      in Compositor::handleKeyPress. That is to call iniSurface::sendConfigure upon presing F9.
      4. Client is all black

      Both compositor for Qt5 and Qt6 are attached.
