This is still Ivybridge. Since you said yourself this still worked on TW previously using the Intel SNA driver, it would be worth a try to install xf86-video-intel package on your freshly installed TW. If this doesn't help, this looks like a regression in the kernel driver. Or with Plasma we now have completely different requirements for the desktop WRT 3D acceleration, so trying to use Cinnamon desktop again might be the first option. -- You are receiving this mail because: You are on the CC list for the bug.

B. --- I should also mention that I ran the same TW with Cinnamon installation on this laptop for a long time, like 3 years, and I just did the fresh TW install with Plasma a few days ago. It's my daily driver computer. -- You are receiving this mail because: You are on the CC list for the bug.

Since my last post here, I've been running the Intel driver still, but with the Plasma compositor using the Xrender backend. It's looking tentatively much more stable. I'll switch it back to the openGL backend soon to see if it starts freezing again.

Ok. Any news you can share with us on this topic? -- You are receiving this mail because: You are on the CC list for the bug.

Ok, I just now had a freeze with the openGL 2.0 backend, and I had to kill Xorg to recover. Looks like it's the same as the references I linked in #c4, something about the way Kwin uses openGL exposes an underlying flaw in the Intel driver. -- You are receiving this mail because: You are on the CC list for the bug.

Ok, so no good news. But nevertheless thanks for giving it a try!

Also thanks to you for looking into it. Please let me know if you need any more information. -- You are receiving this mail because: You are on the CC list for the bug.

Desktop stays visible, mouse can move, music continues playing as normal, but no interaction possible. No CPU load on X11 nor kwin. Just now I managed to restore my desktop by going to a virtual terminal, searching for the kwin_x11 process and killing it with `kill -9` then restarting it with `kwin_x11 --replace`. I also killed plasmashell and restarted it the same way. No lost work fortunately, for once. It started happening after I reinstalled Tumbleweed about a month ago. Hardware is Dell XPS 13 9333 with Intel driver (I'll attach hwinfo). Compositor is on openGL 3.1. This is without any workarounds. Before the reinstall, the desktop was stable. S.B. did you try switching to UXA yet ? I might try that next as I think I had it before the reinstall. I also remember having worse performance with UXA with Youtube which is why I didn't reenable it yet. -- You are receiving this mail because: You are on the CC list for the bug.
