I think I found out the problem.it's the new w10 widget news and interests.I reactived it and now MHC works when I disactive it ,I got problems whit MHC.

That is really weird. I don't have any logical explanation why that app would have any effect on MPC-HC.

i think the problem is the adavance scaling setting of W10 that I am using 160%,infect If I set it to 100% MPC-HC works like charm.For The moment i disabled the lav icon .could you make a test setting your adavance scaling setting to 160% to try to replicate the bug?

Does it also happen at 150%?

Check if this solves the problem:

it doen't work.have you tried to replicate the bug?

I have been able to replicate it. With Windows build 19042.1052
I did not yet have time to investigate what exactly goes wrong.
