Bug ID: 370264 Summary: KWin crash with "No provider of glFenceSync found" Product: kwin Version: 5.8.0 Platform: Compiled Sources OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: effects-various Assignee: kwin-bugs-n...@kde.org Reporter: stalk...@gmail.com After upgrade to kwin 5.8 "graphic effects" has not worked. I pulled KWin from master and builded by hand. All problem in void GLVertexBuffer::endOfFrame() (kwinglutils) when we try call glFenceSync(GL_SYNC_GPU_COMMANDS_COMPLETE, 0); Everything started to work fine after KWIN_PERSISTENT_VBO=0 . Currently I am using EGL on Intel Haswell (mesa, libdrm, xf86-video-intel from git) PS We realy can use glFenceSync under EGL?
