Bug ID: 456372
Summary: kwin_x11 (EGL): Creating the OpenGL rendering failed:
"Invalid QOpenGLContext::globalShareContext()"
Product: kwin
Version: 5.25.2
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: egl
Assignee: kwin-bugs-n...@kde.org
Reporter: da...@protonmail.com
Target Milestone: ---
kwin_x11 works perfectly with KWIN_COMPOSE=O2 (GLX) and everything works, but
if I use KWIN_COMPOSE=O2ES (EGL), it fails with "Invalid
QOpenGLContext::globalShareContext()".
Operating System: Linux
KDE Plasma Version: 5.25.2
KDE Frameworks Version: 5.96.0
Qt Version: 5.15.5
Kernel Version: 5.18.9 (64-bit)
Graphics Processor: NVIDIA GeForce RTX 2070 with Max-Q Design/PCIe/SSE2
kwin_core: Compositing forced to OpenGL mode by environment variable
kwin_core: Forcing EGL native interface as OpenGL ES requested through
KWIN_COMPOSE environment variable.
kwin_core: Attempting to load the OpenGL scene
kwin_platform_x11_standalone: Global share context format:
QSurfaceFormat(version 4.6, options
QFlags<QSurfaceFormat::FormatOption>(DeprecatedFunctions|ResetNotification),
depthBufferSize 24, redBufferSize 8, greenBufferSize 8, blueBufferSize 8,
alphaBufferSize 0, stencilBufferSize 0, samples -1, swapBehavior
QSurfaceFormat::DefaultSwapBehavior, swapInterval 0, colorSpace
QSurfaceFormat::DefaultColorSpace, profile
QSurfaceFormat::CompatibilityProfile)
kwin_scene_opengl: Creating the OpenGL rendering failed: "Invalid
QOpenGLContext::globalShareContext()"
kwin_core: Starting without compositing...
Any idea? Thanks.
