please help. how can i fix this.
If you aren't using 3.3 update the 3.3. If you are using 3.3 then it is likely a problem with OpenGL drivers.
@hamishwillee Aren't there docs on the alternate startup shortcuts for Windows. I can't seem to find it.
@DonLakeFlyer Yes, they are here. They are also linked from the Download and Install > Windows section (see the note at the end)
Ok, so take a look here: https://docs.qgroundcontrol.com/en/Support/Support.html#opengl_troubleshooting for troubleshooting Windows builds. Try the alternate shortcuts for startup.
