Windows: GPU works in 130.0, but doesn't work in 130.1

[cztomczak]

After removing "disable-gpu" switch in settings.json user was able to get GPU accelerated rendering working in version 130.0, but it doesn't work for him in version 130.1.

User reported on old forum here:

There are two differences between 130.0 and 130.1 that could possibly affect this:

1. CEF headers updated in this commit: 9cecffe
2. Main window creation logic changed: 8ceda28

Need to re-check if CEF binaries are in proper versions. In both 130.0 and 130.1 I had strange issues with GPU, and it seemed it was caused due to nvidia drivers, however I couldn't reproduce them in upstream cefclient/cefsimple apps which was puzzling.

Some newer CEF versions required app compatibility manifest for GPU detection:
https://source.chromium.org/chromium/chromium/src/+/main:build/win/compatibility.manifest;l=1?q=compatibility.manifest&ss=chromium

Tutorial still mentions that manifest:
https://bitbucket.org/chromiumembedded/cef/wiki/Tutorial#markdown-header-windows-build-steps

However there is no such manifest in CEF 130 or latest CEF 132. CEF 127 apparently had it included.

Manifests can be found in Standard Distribution binaries in tests/cefclient/win/ subfolder.

Possible fix for GPU issue:

1. Create "phpdesktop-chrome.exe.manifest" file next to main executable with these contents:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">

  <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">

      <!-- This tag is required for XAML islands usage in the process for media scenarios. -->
      <!-- This version corresponds to the Windows 10 May 2019 Update. -->
      <maxversiontested Id="10.0.18362.0"/>
    </application>
  </compatibility>

2. Remove "disable-gpu" switch from settings.json file.
