[5.6.1] Render issue on some Android devices

The Android devices currently experiencing this issue have the GPU: Mali G77.

The game is compiled in Development mode.

There are two scenarios:

1. After the first installation and launch, entering the game’s lobby scene displays normally;
After exiting the game and launching again to enter the lobby, the scene appears washed out/white.
Deleting the RHICache\Vulkan Cache directory under the game directory on the phone, and then entering the game again, the display returns to normal.

2. After the first installation and launch, entering the game’s lobby scene displays normally;
At this point, entering another game scene, and then returning to the lobby scene, it also appears washed out/white.

Where is the problem? Are there any solutions? Thank you!

目前出现问题的Android设备的 GPU:Mali G77。

游戏为Development编译。

有两种情况:

1,首次安装启动后进入游戏中的大厅场景,显示正常;

退出游戏后再次启动进入大厅,场景显得发白。

将手机上游戏目录下的 RHICache\VulkanCache 目录删除,再次进入游戏,显示正常。

2,首次安装启动后进入游戏中的大厅场景,显示正常;

此时进入另外一个游戏场景,然后再返回到大厅场景,也是发白的情况。

问题出在哪?有没有解决的办法,谢谢!
