Description Timo Aaltonen 2014-03-13 11:03:20 UTC
When the screen contents change there are short stripes in the area that changed, like when moving/resizing a window.

The stripes vanish over time, within a few seconds. Attached a short video of it.

With the current bios version it's happening only after a S3 cycle, before it was happening always.

running current nightly

just for the record, this can be seen with 3.13/3.14 too, so it's not a regression on nightly
