I followed Zeno Bokor's fix for a different problem and it solved mine, too!
"Try disabling OpenGL Drawing from Edit->Preferences->Performance"
Thanks...that worked for me not being able to see images at all, in any size.
Keep in mind that OpenGL should be working for you, and that disabling it is a workaround, not a fix. With it disabled you lose some OpenGL-specific features, such as smooth zooming and panning, brush size/hardness gesture preview...
Check your video drivers for updates from the manufacturer. New drivers are still coming out that fix bugs like this.
I understand that...and I did check for updated drivers. My drivers are up to date.
It was working fine...I'm not sure what happened. I only use it to write classes, so I'm mostly confused. The issue is I still can't see anything with Open GL active. I'm still working on figuring out what the problem is.
