I have the same problem . I did as second lifes error message suggested . I updated graphic drivers that didn't help. I then uninstalled and reinstalled used windows drivers and AMDs both, neither one fixed the problem. I finally took my pc to a tech and he was lost himself on what it could be. I finally called AMD RADEON and he said it was caused by windows update that came out around Nov 23, 2017, Since my graphics card does not have supported software for windows 10. The only solutions he could suggest and said it may or may not work was to reinstall the drivers for that video card the oldest one u can find. The date being 2015. from the url site that comes up when u select to update drivers when u are in Device Management. I am sorry I can not recall what it is right now and I am on a different computer. If that didn't work then he said only solution would to upgrade my graphics card. Mine is a 4524. It worked great in second life for over a year till this windows update. So ANICENT or not it was doing the job prior to this
