Comment 53 for bug 881046

I wonder, why the maximum panning size is so driver dependent.

My ATI Radeon HD 3450 had a maximum panning size of 8192x8192 with the open source "radeon" and "radeonhd" drivers. With AMD's ATI Catalyst 13.1 Legacy driver I only have a maximum of 1920x1920. The monitor's native size is Full-HD (1920x1080) and it's connected via Dual-Link-DVI.

$ xrandr -q
