gui program cpu consumption is too high #14691

Open xiaoshengduan opened 2 years ago

xiaoshengduan commented 2 years ago

The clock example, or most gui examples, have problems with excessive gpu and cpu consumption。 Compared with the same examples in other languages such as rust and golang, it is more than 10 times higher

v -autofree -prod -stats clock.v

Almost all gui demo programs have this problem
