Starcraft 2 Ultra Video Card Review - Page 2

The glitch can be reproduced most easily on a two monitor setup, by rapidly sliding the mouse across the bottom edge of the desktop such that it crosses display boundaries repeatedly until the glitch occurs, the glitch will appear on the left monitor (the right monitor will remain unglitched), on a single monitor setup it is much more difficult to trigger but can still be triggered by very rapidly moving the mouse between the top left and bottom right corners repeatedly (a 5600 or 5700 DPI gaming mouse is ideal for this, yet still challenging), which also works for triggering it on the rightmost monitor in a multimonitor setup.

The glitch occurs separately on each display (each one has its own glitched/not-glitched/differently glitched state).

This glitch occurs when moving the mouse across monitors at the very bottom edge of the desktop.

The glitch persists regardless of which cursor image is displayed, all are displayed wrong (looks as if a scroll register is messed up), mouse pointer size becomes 16x16 even if the image appeared to be smaller previously, and the image will often repeat in some way to fill out the allotted space.

The mouse pointer size does not change (other than the padding to 16x16 pixels as described above).

The animated busy pointer illustrates how the glitch is scrambling the pointer, and is perfectly captured in Willis's picture, the animation looks kind of like it is showing on shards of broken glass, every pixel of the pointer has its place, but the placement is wrong.

The way the image is scrambled is not completely consistent, the same image might look different each time the glitch triggers - but will be consistent as long as the glitch is present.

One can cause the glitch to mutate to different forms of image scrambling by reproducing the same conditions that trigger it in the first place.

One can glitch a single monitor by itself by moving the pointer extremely rapidly (5600 or 5700 DPI gaming mice are ideal for this purpose) between the top left and bottom right corner of the monitor repeatedly until the glitch occurs.

The glitch persists across disabling/enabling monitors.

Each monitor's respective variant of the glitch belongs to the respective ACTIVE monitor list, this means that if you glitch two monitors (challenging!) you can disable the lower numbered monitor and the higher numbered one will now demonstrate the first monitor's variant of the glitch, reenabling the first monitor restores the glitch variants to their rightful places, disabling the second monitor has no effect on which variant the first monitor shows.

The glitch does not affect any displays hooked up to cards whose chipsets are not ATI.

The glitch has occurred for many people for years now, on catalyst versions ranging back to 9.11 if not earlier.

The glitch still occurs on 10.6 as of this writing.

The glitch occurs at the following resolutions: 1280x800, 2560x1600, 1920x1080, 1680x1050, and probably all others.

The glitch occurs on all types of video port.

The glitch disappears on a reboot (but of course can occur again).

The glitch occurs on Windows 7.

The glitch does not occur on Linux.

Edit: corrected earliest catalyst version to 9.11.
