Comment 76 for bug 1432194

Same issue here....bitten by both bugs on a Toshiba Satellite E45-B4100..

3.16.0.34 - garbled text, inability to even upgrade to proprietary Intel drivers for the HD5500...3d rendering of applications like google maps or steam browser are broken and distorted.

Upgrading to kernel 3.16.0.36 results in boot lockup.

Installing 15.04 (3.19.0-15-generic) and the video is normal...no more missing text or weird artifacting of folders on the desktop. Too bad this isn't fixed in LTS as either bug renders the laptop fairly unusable or unstable.
