Thanks for your responses. I have unloaded and reloaded the lasted version. I have run sfc/scannow and dism. There are no corrupted files. When I remove start10 or even just start10 unload, the corruption immediately disappears. I am also running nvidia whql certified video driver and the prev build just in case.
I have uninstalled rebooted, reinstall rebooted. It looks fine until I open open the menu. Im now running 2021H2 Win 10 with no improvement.
Also I forgot im running fences too, but i dont think this is relevant.
Lastly, I have been chasing a lingering low windows explorer when opening the context menu (right mouse click).
I have used shexview to see all of them and disabled all of them. Explorer runs much faster. Im going to try start 10 all over again
Any suggestions would be welcomed.
