How to fix that white points on the screen?
I have that only in unity 5.
Im using free version.
Without specific informations such as target platform, testing platform, used image effects etc. noone will ever help you.
Go to Edit->Project Settings->Player
Under the “Other settings”, choose between the different rendering paths to see if it help fix the issue
If it is set to “deferred” sometime white dots appear
if is is set to “Legacy Deferred” sometimes it will fix the issue
will apply FXAA helps?
