So, I was playing spiral Knights a month or 2 back, then had a long downtime. Now, My text is garbled and silly.
Here Is my graphics details straight for Intel Update.
Product Detected Mobile Intel® 945 Express Chipset Family
Current Driver Installed 6.14.10.4926
Your driver is current.
I have Not tried updating Java yet, so I'll try that.
Edit:: Just Updated Java, Little Better than before, but still garbled.

That totally looks like an issue with your graphics driver. The 945s seem to have issues with the game--they don't have full 3D support or something? Even text fails to render properly.
Have you also manually checked Intel's website for a new driver? On my Vista computer, it fails to detect new versions for whatever reason. When I get home in a few hours I can check for you.
What does the game look like when you log in? If you could provide us with more information that would be great.
EDIT: You can try looking for an updated driver here; I didn't know your operating system, so I couldn't find the specific one you would need.
What was the date on the driver version you currently have? The latest on the Intel website is from December of 2010.
