Expand the cocos2d-x3.0 bottom support etc image format, the game in the model using etc format Picture replacement. It could have been run on a machine with Lenovo S880, the graphics card type POWERVP SG X 531, but had to go back to the game loading model after switching to the ETC picture.
At present, most of the other models do not have this problem, only some of the machines will flash back. Preliminary judgment may be a problem with the graphics card, the machine's graphics card type is PowerVR SGX 531. I do not know that you have encountered the same or similar problems.

Summarize the reasons that may cause the game to flash: 1. Resources are not optimized, resulting in the use of too much memory, the system is forced to quit; 2. The resource is too large to burst memory to cause a flashback; 3. The picture is too large (some low-end models only support the maximum picture size is 1024, then this time will be noted); The picture is not the power of 2, some graphics card is not supported by the power of the non-2 side of the picture (the reason for this flashback is because the use of etc material, the graphics card does not support etc picture is not 2 power to cause, but the support of PNG is not 2 power, so look for a long time to find this problem).
