[Bug 366300] Re: plasma paint errors, crashes with SIGSEGV

[obsidian]

Have confirmed that downgrading to the 2.4 driver (per instructions
here:
https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4) has
no effect, positively or negatively, on the problem.

I have also confirmed that, once the display corruption begins, the
entire Amarok window is often unusable, rather than just the border.
Interesting.

I am doing some more testing, and trying to confirm that this problem is
distinct and unrelated to graphics performance and/or stability issues
widely reported against the intel driver. Truthfully it is much more
serious, since the desktop is nearly unusable within minutes.

I wonder if this may be a problem in QT/KDE/Plasma, that manifests in a
multiple monitor configuration. That is my normal config, and it was
fine in 8.10 on this hardware, aside from occasional, highly benign
plasma panel placement weirdness, and the need to configure it manually
with xrandr.
