Fresh system install, with correct display driver from Intel (22.214.171.1245). Clicking "Update driver" merely results in a message saying the driver was already up-to-date.
After resuming from hibernate the entire screen flickers. This is especially noticeable while using IE9 (which has hardware acceleration enabled by default) on Google maps, in particular while typing in an address in the map search field (the flickering is much worse under these circumstances). Note that sleep worked fine, only hibernate causes this issue. Restarting "fixes" the problem temporarily until the next hibernate-resume.
Aero is enabled. This is on Windows 7 (Pro) 32-bit, on an Acer Aspire One D270-1998, with the Intel N2600 (which has the Intel GMA 3600 built-in).
