Do you really hope to get an answer to this kind of message ?

More details about your configuration would be welcome. Mac or Windows ? Which version of LR ? Which version of the OS ? Does this happen with all files ? Only with a particular file type (JPEG, TIFF, RAW) ? Or only for files from a given camera ? Did you update your display driver recently ? NVidia or something else ? Did you check the "Use Graphics Processor" option in Preferences | Performance ? Did you try after unchecking it ?

Almost certainly a graphics driver issue.

Try updating your graphics driver directly from the AMD or nVidia website..

If that doesn't work, try disabling Use Graphics Processor.

Thank you!! I disabled the Graphics Processor and that worked! Is there any disadvantage to having it disabled? Thanks for your help :)

That depends. Using the graphic card processor implies to exchange data between the CPU and th GPU.
If the exchange rate is not fast enough, the lost due to the exchange can be bigger than the process improvement due to the GPU, and in this case using the GPU can degrade the developpement process performance in LR.
ITOH, if the exchange is fast enough and/or the GPU powerful, the GPU benefit will be higher than the lost due to the data exchange. In this case, using the GPU will improve the developpement process performance.
The only way to know for your configuration is to try both and see which gives the best result.
