If a power cycle is required, then the main issue is not a Qt bug. It's either a hardware problem or a driver problem.There may be a minor Qt bug that causes the driver to make something even worse. But the main issue is not in Qt. My guess is OpenGL drivers. Perhaps I found the cause of the hangs. It seems GPU runs out of memory. I launched my application and though an ssh connection I printed out multiple times the GPU free mem using: In the exact moment the gui freezed I read this: Relocatable heap version 4 found at 0x1f000000 Of course I'm pretty sure I don't need all 492 MB :) I hope, at least! Perhaps my app is bad designed and I waste memory somewhere. Please, I kindly ask some hints to understand how should I debug this situation. What would you do to find out where is the problem? Because the ui is designed in QML I bet I need to search in there, not in the C++ "logic" side, don't I? Thanks for your help Marco |
