Unfortunately nouveau's mesa driver isn't particularly good at handling that issue, which causes it to get much worse failures down the line. If you have an IGP, please increase the size of the "VRAM" allocation. Realistically, I doubt the plasma5 use-case fits well with nv30/nv40 hardware. You're taking a 2015 compositor and running it on 2005 hardware. You could (correctly) make the argument that nouveau should do a better job at this -- and you'd be right. However volunteers aren't falling over themselves, rushing to fix these issues.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
