--- Comment #7 from Igor Poboiko <igor.pobo...@gmail.com> --- It was built with GLX support, and epoxy found it. But KWin didn't list it in org.kde.kwin.Compositing.supportedOpenGLPlatformInterfaces, because QtOpenGL was built with GLES2 support, and QOpenGLContext::openGLModuleType() was LibGLES. I had to rebuild it without GLES2 and after switching to GLX backend these glitches (as well as crash with disabled compositing) disappeared. This issue was quite frustrating.
