[etsek]

• cocos2d-x version:cocos2d-x-4.0
• devices test on: iOS 14 (iPhone), macOS 10.15.6
• developing environments
  • NDK version:
  • Xcode version: 12.0, 11.7
  • VS version:
  • browser type and version:

Steps to Reproduce:

1. Build cpp-tests, run test 41 (Node:RenderTexture)
2. Try Save Image PMA, Save Image Non-PMA: assertion failure

Image saved image-pma-0.png
Assert failed: reference count should be greater than 0
Assertion failed: (_referenceCount > 0), function release, file /Users/xxxx/xxxx/cocos2d/cocos/base/CCRef.cpp, line 89.

3. Try Clear to Random, Clear to Transparent: exception raised (EXC_BAD_ACCESS)

RenderTargetMTL::Attachment RenderTargetMTL::getColorAttachment(int index) const
{
if(isDefaultRenderTarget() && index == 0)
return {DeviceMTL::getCurrentDrawable().texture, 0};
auto& rb = this->_color[index];
return RenderTargetMTL::Attachment{static_cast(rb) ? (id)(rb.texture->getHandler()) : nil, rb.level};
}

thanks, should be fixed by the latest commit

Thanks, I tested the first issue (save image) and indeed it has been fixed. The second issue however (clear) remains even after Commit 755a0fb. @halx99 can you check please?

[halx99]

I will check it later

Clear() works as expected now, thank you!
