Kali linux environment problems

I have a problem with my Kali Linux machine that's really weird. Basically, I can't right-click on my desktop, I can't alt+tab to other windows, I can't close a tab and I can't even see any program properly everything seems weird. The problem is not about resolution I have checked that already. I'm thinking some package is responsible for this issue(maybe the Nvidia driver). Everything was working perfectly yesterday and today I open the machine and I find this problem. If anyone knows how to fix this, please help me. Thanks.
