[デスクトップ版]5.7に更新後ハードウェアアクセラレーションが効かない
-
・Vivaldi ご利用環境、OS と Vivaldi のバージョン(何bit版か含め)
cpu--core i7 3770k グラボ--gtx750ti lubuntu20.04-64bit・再現手順（ステップ・バイ・ステップ）
5.6.2867.62-1から5.7.2921.53-1に更新直後から
ハードウェアアクセラレーションが全て効かない
vivaldi://gpuを見るとopenGLすら無効になっている・本来あるべき挙動
DRDC、video encode、webgpu以外
アクセラレーションが有効になっている・実際の挙動
全て無効になる（openGLすら無効）・補足情報
数回バージョンを戻したり最新にしたりしたが改善しない
グラフィックドライババージョンを変更しても変わらない
現在は5.6にて使用中（もちろんアクセラレーションは有効）
以下のコマンドでバージョンを固定している
$ echo vivaldi-stable hold | sudo dpkg --set-selections
他のchrome系ブラウザ（chrome、brave）では発生していない不足部分があったらご指摘ください。
よろしくお願いします。 -

lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource.
use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details.
vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible.
disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet.

報告・詳細情報の共有、ありがとうございます
社内にて同環境にて発生している報告が見られましたので、本件も共有させていただきました。 -
@ahojo だいぶ時間が経過しましたが・・・変化があったので報告しておきます。
ずっと同じバージョンでも問題ないかと思ってましたがどうしても不具合が出てきます。特にアドオン関係でもう追加などできない状態です。
そこでダメ元で最新バージョン6.6.3271.50 (Stable channel) stable (64-bit)を試したところ起動すらしませんでした。
他のブラウザでいろいろ検索したところたまたま目に入った起動オプション（--v=1）があったのでそれを意味も分からずなんとなく追加したところなんと無事に起動できました。
ちゃんとgpuの項目も設定できてます。
設定画面がチラついたり起動時に特定ページを指定すると起動しなかったりと少々問題はありますが、ここでは触れないことにします。
設定フォルダのバックアップをとりながら以前と同等の環境まで戻すことができてます。関係してるかは分かりませんが今まで普通に動作してたchromeとbraveがある更新を境に全く起動しなくなったのもありますから
もしかしたらvivaldiだけの問題ではないかもしれません。
chromiumは特に問題なく最新版が動作してます。
