This can be observed from the following video, where I am highlighting global menu entries with the mouse: https://www.dropbox.com/s/ez2v03oetppecgx/VID_20150324_020612.mp4?dl=0 A similar effect can also be observed while dragging windows around near the top of the screen. 2) The virtual terminals no longer take up the full screen area, and are surrounded by a pattern which appears similar to noise or "snow" on old TVs. Here's how it appears on my screen: https://www.dropbox.com/s/7hj8qi3w3qc35jb/IMG_20150405_155434.jpg?dl=0 While these two issues seem quite unrelated, they both seem to happen _only_ after a suspend/resume cycle, so the underlying issue might be related between them.
