Phoronix: Clear Linux Makes Caffe Deep Learning 10% Faster; Also Discovers XFWM4 Compositor Bug

Intel's Clear Linux distribution hasn't been at rest this summer but they've continued working hard on various performance optimizations and improvements to their distribution...

Props to Phoronix and Michael for providing the PTS infrastructure to run these tests and props to Intel for using it to make their distro better and help improve the quality of other open source projects too.

Good work from the Intel Open-Source Technology Center guys. About the XFWM4 bug, it seems the XFCE high priest was wrong again.

So they just disabled compositing?

IIRC other major compositing WMs like mutter disables compositing for fullscreen apps. Probably such thing is not implemented in XFWM4.

indeed this is our short term workaround while we try to figure out how to fix this properly (and then get that upstream).

XFWM4 has similar functionality, but the bug so far is that the heuristics to detect when something is fullscreen is not triggering for the cases we looked at (the various PTS gaming/graphics tests). For now we've disabled compositing but we're still poking at seeing if we can correct the heuristics

No way. It must be some ubuntumagic beeing (correctly) ported to Clear Linux. Neither XFCE nor Debian can be affected by any bug.

I'm not criticizing XFWM4. Its perfectly normal for a bug to pop up once in a while, even in the most perfectly formed* software.

* Best practices, full test coverage and the works

I assume you weren't following many forum threads lately? His reply was sarcastic.
