Nikolay <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #6 from Nikolay <[email protected]> --- Confirmed on Fedora 44 with Kamoso 26.08.1, Plasma 6.7.5 (Wayland), GStreamer 1.28.7 and NVIDIA 615.71.09 (RTX 4060 Laptop). The preview is black only when the NVIDIA GPU renders (MUX switch set to dGPU); in hybrid mode it works. The cause is in GStreamer's GL upload of DMA-BUF frames on the NVIDIA driver: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/work_items/5313 (the maintainer agreed to fall back to raw upload when binding the EGLImage fails). Workaround on laptops with two GPUs: run Kamoso with Mesa's EGL, e.g. in a copy of org.kde.kamoso.desktop in ~/.local/share/applications: Exec=env __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json kamoso -qwindowtitle %c -- You are receiving this mail because: You are watching all bug changes.
