Firstly, sorry everyone for bad English.
I have a problem with all my projects - at some unknown point, when you start previewing them, they can break at random point - screen turns black, debugging stops counting time, ticks and everything else. Construct editor also crashes, and after that layout preview stops loading - just black screen with small sad smile in top left corner. I don't understand what is the problem - it happens in really random time (can break after 2 seconds of preview or can stay fine for all the time I play game), that happens even after I disable all events in project. When playing game in browser, it also happens, but after crash you can continue to play normally. Also, in case with my last project, it started to happen in also random moment. It was fine about week ago, now it crashes in almost every run (i wasn't working with project in that week so nothing changed). Maybe problem with my computer? Didn't found anything same in other topics
Upd: just got detail that if project runs not in fullscreen, or fullscreen mode is "letterbox scale", then nothing crashes. Maybe it's related to rendering or something? Also, i tried to change fullscreen quality from low to high, and looks like everything started working correctly, because before changes game crashed almost every time, and now for 10-15 launches it hadn't crashed even 1 time
