Description Yury Zhuravlev 2016-10-07 21:35:48 UTC 
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?

Reproducible: Always
