hi,

i've noticed on kernel 2.6.35.y some weird screen blinking during
e.g. <alt-tab> on kde4 with enabled accelerated desktop effects.

i've started git bisect between good-v2.6.34 and bad-v2.6.35-rc1
and after few steps git-bisect jumps to commit before v2.6.34.

[~/src/linux/linux-2.6]$ make kernelrelease
2.6.34-rc6-00551-g7a6cb0d

[~/src/linux/linux-2.6]$ git bisect log

is it normal that bisect selects next step outside initial range?

BR,
Pawel.
