I'm using Acer Aspire : ATI Radeon 4k series(graphics, ATI\AMD Proprietary Graphics software installed), 3GB(RAM) and Ubuntu 12.04(OS). Initially graphics were good but recently after an update, some graphic features seem to be missing.
- Dash used to be full screen, now only part of the screen!
- Exit, Maximize and Minimize buttons are missing in every window
- ALT + TAB - lost its graphics
- Superkey + W not functioning at all
Checked with the update manager for recent updates but I couldn't find any that made change to the graphics. What could be the issue ?
