Failed to create OpenGL context for format QSurfaceFormat(version 3.0, options QFlags<QSurfaceFormat::FormatOption>(DeprecatedFunctions), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior QSurfaceFormat::SwapBehavior(DoubleBuffer), swapInterval 0, profile QSurfaceFormat::OpenGLContextProfile(CompatibilityProfile)) . This is most likely caused by not having the necessary graphics drivers installed. Install a driver providing OpenGL 2.0 or higher, or, if this is not possible, make sure the ANGLE Open GL ES 2.0 emulation libraries (libEGL.dll, libGLESv2.dll and d3dcompiler_*.dll) are available in the application executable's directory or in a location listed in PATH.
Hi Ingrid, This isn't a bug in Krita: it simply means that essential system libraries are not available on your system. You need to install updated drivers for your GPU.
