When play in viewport all good, after clicking Launch game - appear white pixels. What to do?
Hmm, looks strange. Do you also get those pixels when you play a template map?
-which engine version do you use?
-what are your pc specs?
-do you use the “epic” quality settings? 
-4.6
-amd x4 651 quad-core 3 ghz GTX 650
-medium
Pixels appear when I start the game in full screen
What happens when you set the scalability settings to epic? + do you also get them in a template map? + are they “moving” or permanently on the same place? + what happens when you package the game and test it?
