I have noticed something weird lately. I create games and other interactive content for museums, exhibitions and showrooms. So I make apps that are active around the clock every day. For some time now, my apps have been crashing at irregular intervals. This applies to both new apps and ones that have previously worked around the clock for several months straight. This applies whether I run them on Windows or Linux. The crash appears as a black screen with a small white icon in the upper left corner of the screen. Do you have any idea what could be causing this?
