--- Comment #3 from Fabio Coatti <fabio.coa...@gmail.com> --- Likely; however I got this error message by setting KWIN_GL_DEBUG 1 libkwinglutils: Failed to compile vertex shader: "0:2(1): preprocessor error: #version must appear on the first line\n\x00" libkwinglutils: Failed to link shader: "error: no shaders attached to the program\n\x00" kwin_core: OpenGL 2 compositing setup failed kwin_core: Failed to initialize compositing, compositing disabled I tried also to set QT_LOGGING_RULES "*.debug=true" but I'm not sure that this change has been picked up, some suggestion on how to get more debug messages? -- You are receiving this mail because: You are watching all bug changes.
