--- Comment #24 from geisserml <geisse...@gmail.com> --- > I think I can now prove your guess that it's an upstream bug in the graphics > driver: > Running QtQuick apps (e. g. Elisa) with the environment variables > `QT_XCB_FORCE_SOFTWARE_OPENGL=1 QT_QPA_PLATFORM=xcb` fixes the problems. >From looking at the console output, when not using the Software OpenGL flag, there are a lot of warnings about "Problematic vertex shader source code" and messages like "This file is intended for desktop OpenGL version 4.5 or greater". So probably the cause is code written for a newer version of OpenGL than what I have: ``` QOpenGLShader::compile(Vertex): 0:14(10): error: GLSL 4.50 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.40, 1.50, 3.30, 4.00, 4.10, 4.20, 1.00 ES, and 3.00 ES *** Problematic Vertex shader source code *** [...] // This file contains common directives needed for the shaders to work. // It is included as the very first bit in the shader. // Important: If a specific GLSL version is needed, it should be set in this // file. // This file is intended for desktop OpenGL version 4.5 or greater. [...] ``` -- You are receiving this mail because: You are watching all bug changes.
