What happened?

WebView2のVer131.0.2903.xx以降、PDFの表示が崩れてしまいます。
Ver130.x以前では正常にPDFが見れました。ちなみにプログラムから開くでEdgeでPDFを開いた時も表示が崩れます。Acrobatで見ると正常に表示されます。Ver131以降ランタイムが消えるなどの事例があるのも拝見しましたが、関連しているバグなように見えます。Xでも同様の反応をしているユーザーがおり、Microsoft側のバグであると確信しております。早急な修正を希望します。WIn11&Win10環境どちらでも現象は発生します。Ver131をアンインストールし、Ver130より古いバージョンで試した所、PDFは正常に表示されたのでVer131の問題と思われます。

Adding English translation:

After Ver. 131.0.2903.xx of WebView2, the PDF display is broken.
In Ver130.x or earlier, PDF files could be viewed normally. By the way, when you open a PDF in Edge by opening it from a program, the display is broken. It is displayed normally when viewed in Acrobat. I've seen cases where the runtime disappears after Ver131, but it seems to be a related bug. There are users who have had similar reactions to X, and I am convinced that it is a bug on Microsoft's side. I hope it will be corrected as soon as possible. The phenomenon occurs in both WIn11 and Win10 environments. When I uninstalled Ver131 and tried it with a version older than Ver130, the PDF was displayed normally, so it seems to be a Ver131 problem.

Thanks for reporting the issue. Can you please check if the issue is specific to a PDF or is it happening with all PDFs? If issue is specific to PDF, is it possible to share the details of the PDF?

恐らくですが、埋め込みサブセットされていないPDFで起きていると思われます。
以前のバージョンでも埋め込みサブセットされていないPDFで代替フォントが使用されるという現象は確認していました。
代替えフォントが使用されるため、辛うじてPDFの内容は確認できていましたが今回のバグでは白抜けというかPDFの表示自体がうまくいっていないような現象を確認しています。例えば「株式会社ABC」という表示がまったく抜けてしまっていたりというような感じです。数字の表示はうまくいっているようです。(アルファベットも?) 日本語がうまく表示されていないかもしれません。
