https://bugs.kde.org/show_bug.cgi?id=358750 --- Comment #25 from Martin Gräßlin --- The problem should only be in the EglOnXBackend, so a qputenv("EGL_PLATFORM", "x11"); could be added, if it helps. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=358750 --- Comment #27 from Niels Ole Salscheider --- Yes, this would be sufficient. For mesa at least, since it queries the environment variable in eglGetDisplay. We already use EGL_PLATFORM for the hwcomposer backend and the

https://bugs.kde.org/show_bug.cgi?id=358750 --- Comment #20 from Niels Ole Salscheider --- No, the current code tries all EGL drivers (which is only drm), but it only tries one platform for each driver. This platform is either what is set by the EGL_PLATFORM env
