           Summary: Cemu Shader Cache Corruption Displaying Solid Color

shader cache corruption

Background:
Using Cemu emulator with shader cache functionality breaks after commit
11e16ca7ce0. Screen display only solid colors with very low fps.

System:
AMD Ryzen 2600
RX580
Linux 5.0.9, amdgpu, mesa master

How to reproduce the issue:
1. Run Cemu, enable shader cache functionality
2. Play a game then let shader cahce be generated. Game can be played normally
and shader can be built normally. No graphical issue is found at this stage.
3. Quit Cemu
4. Play the same game again utilizing the generated shader cache
5. Game display shows flickering solid colors as shown in this ticket
attachment. 

Expected result:
Playing the same game with previously generated shader cache should display the
correct graphic instead of flickering solid colors.

Can you address this issue?
