On iOS https://itunes.apple.com/us/app/geogebra-3d-graphing-calc/id1445871976 you need to have a device with iOS 11 that supports ARKit ie iPhone 6S / iPad 5 or later: https://developer.apple.com/library/archive/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/DeviceCompatibilityMatrix/DeviceCompatibilityMatrix.html

My computer crashed, where's my work?

If you were using GeoGebra Classic 5, have a look in the computer's temporary folder and look for the most recent file like GeoGebraUndoInfo6533063557894725659.ggb

Quickest way in Windows: http://www.tomshardware.co.uk/faq/id-2082907/temp-folder-windows.html

then Enter.

Graphical Glitches in GeoGebra Classic 5 (Windows)

These are due to a bug in the graphics card drivers. If you can't find newer or older driver that work then you can try

  • setting compatibility mode to Windows XP (Service Pack 3)
  • setting a J2D_D3D environment variable
  • run from the command-line with -Dsun.java2d.d3d=false

See https://help.geogebra.org/topic/geogebra-on-windows-10-graphical-bug and https://wiki.geogebra.org/en/Reference:Command_Line_Arguments
