Problem DescriptionOccasionally Blenders
User Preferences pop-up window either does not show, or when it does is corrupted when accessed from "
File ยป User Preferences" main menu. The likely culprit is a graphics card driver with broken or poorly implemented OpenGL which can manifest in problems displaying multiple layers of OpenGL content (which Blender uses to draw it's interface). Whilst not a fix in of itself, the following tip should allow access to User Preferences, not as an overlay, rather as an 'Editor'.
SolutionFrom any view (typically the 3D View), click the "
Current Editor Type" button far-left of the menu-header under the active window and select "
User Preferences" from the list. If there are no fundamental issues with Blender itself, the view should switch to the appropriate window absent the display issues. If not then it means there is a fundamental problem either with the installation of Blender (in which case re-download and re-install the file, or download an earlier version to see if the same problem exists).
User Preferences not properly displaying when accessed from the "
File" menu
Instead of accessing from "File" menu, select "User Preferences" as a "Current Editor Type" view
