@173619070 Are you on Intel?

@173619070 Are you on Intel?
yes, Intel UHD Graphics 620,i used the Intel graphics card before. then I tried to replace it with an independent graphics card(NVIDIA MX150). and there was no crash now,thanks a lot! but i think it is more efficient to use the vkWaitForFences instead of vkQueueWaitIdle when submit or present, what do you think.

@173619070 210c9dc should fix intel crash.
Wait for fence suggestion I need time to check.
