System became lagging randomly after trivial code change

[zxkmm]

Originally found by @htotoo

A. what happened

The system (or only UI, or UI caused system) got lagging appeared after trivial random code edit.
for example:

1. add one more item in an array, it became lagging, but deleted that item fixed.
2. add an return in a function that should return there, became lagging, and use a bool to bypass following code instead of using return, weirdly fixed.

B. how can tell if current firmware has this issue

1. in the navigation page, the tile appears one by one like having animations
2. in the home page, the time text field flashing when ticking seconds
3. in microphone and recon apps (because these two have many widgets so more obvious), the widgets appears one by one slowly.

C. what we currently found

1.

Seems not related to whether external apps and standalone apps exist or not

2.

make clean or ninja clean, then build won't make differences, but for test, better clean before building

E. discover log

1.

firstly found after #2302 were merged, AKA 8d1fb7c , fixed by workaround in #2307

2.

appeared again in the halfway of work in #2331 but fixed in same PR by use bool instead of return

3.

appeared again in the halfway of work in #2333 but also fixed in same PR by use bool instead of return
