What's the problem? Describe what went wrong.

When saving or loading a savestate on Android, Dolphin will freeze and stop responding.

In logcat, the following error appears:

org.dolphinemu.dolphinemu.debug E/Dolphin: [NativeLibrary] Alert: An error occurred.
    
      Line: 648
      File: ../../../../../../Core/VideoCommon/RenderBase.cpp
    
    Ignore and continue?

This line refers to the assert statement in the following code:

void Renderer::ScaleTexture(AbstractFramebuffer* dst_framebuffer,
                            const MathUtil::Rectangle<int>& dst_rect,
                            const AbstractTexture* src_texture,
                            const MathUtil::Rectangle<int>& src_rect)
{
  ASSERT(dst_framebuffer->GetColorFormat() == AbstractTextureFormat::RGBA8);

When inspecting the dst_framebuffer the color format is R32F instead of RGBA8, causing the assert to fail.

I have commented out the assert and recompiled Dolphin. This fixes the issue. However, since this assert was probably put there for a reason and I'm not familiar enough with Dolphin to locate the root cause I have decided to submit an issue instead of a pull request.

What steps will reproduce the problem?

1. Open Dolphin on Android
2. Enable Vulkan video backend
3. Enable savestates
4. Load one of the mentioned games
5. Save or load a savestate

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, 5.0-11830.

Is the issue present in the latest stable version?

No stable Android version available.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

The last working version is 5.0-10697. The first broken version is 5.0-10707.It has the following desription:

Merge pull request #6321 from stenzek/efb-savestates

Support saving EFB and texture cache in save states

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too.

What are your PC specifications? (CPU, GPU, Operating System, more)

Nokia 8 TA-1012, Snapdragon 835, Android 9 (1 January 2020 security patch)

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
