Upgrading broke KWin compositing for me. Downgrading restores it. Also happened with the AUR full-beta packages. This happens only on my laptop (Lenovo P50, Quadro M1000M, hybrid graphics disable in Bios/only Nvidia card is active). On my desktop (GTX970) the latest release is OK. Manually enabling/disabling compositing has no effect (although the screen to flicker/refresh when trying to enable it manually, it just seems to automatically disable it instantly).

Additional info:
* nvidia 370.23, kwin 5.7.3-1. Testing repos are enabled, system fully up to date.

Steps to reproduce:

Install/update to Nvidia 370.23 (official packages or full-beta from AUR). Restart computer. KDE/Plasma boots, log in, notice the screen flickers a bit like it wants to enable compositing, but it doesn't, and you are left with an uncomposited desktop. No errors/crash from KWin, and its not apparent in the system settings that it is disabled.
This task depends upon

Please note that this affects the OpenGL 3.1/2.0 renders. Using the XRender back end re-enables effects. Let me know if there are any logs/etc I can provide.

I have the same issue with a Quadro K4100M. I've reported the bug to KDE (, though my gut tells me it's an Nvidia issue.

I am sticking with nvidia 367 (long lived branch) with no problems. Nvidia 370 is beta, I think...
For me, short lived branch (and beta) nvidia drivers have been the major cause of instability on my system.

Unfortunately, it is a beta, but, all arch packages (including -lts) apparently were updated to 370.23.

Please try 370.28.

Just tried 370.28 from testing, but it didn't solve the issue for my setup.

Also just updated - still broken for me, too.

Upstream "fixed" it in the 5.7.5 release of Plasma - please close out.
