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?
Reproducible: Always
