Why is V9 so much slower than V8.4? #58

Open RayzzzzzZ opened 2 months ago

RayzzzzzZ commented 2 months ago

use 的lv_port_linux去compile v9.2 widgets demo and v8.4 version。 V9 has obvious stuttering and tearing。

v9 shouldn't be significantly slower than v8. I suspect that there are some differences in the driver or configs.

I've just noticed that the asserts are enabled by default in this repo. Please disable these 3 asserts.
