MetaTrader 5 (build 6182) renders its Marketplace / Signals / News panels with
the Microsoft Edge WebView2 Runtime (Evergreen `153.0.4234.32`). Under Wine on
an NVIDIA GPU the WebView2 browser process starts, the page is fetched
(history shows `file://terminal64.exe/market.html`), but the content is never
painted — the panel and the login pop-up stay blank white. `DU` of
`EBWebView/GPUCache` stays ~300K with a few files, i.e. no rasterization
happens.

--- Comment #1 from brandow <[e-mail]> ---
In mt5 6204 and vanilla git wine I could open the "VPS" and "Market" webview2
windows using webview2 151.0.4129.78 with the msedgewebview2 set to win7
workaround:

wine reg add "HKEY_CURRENT_USER\Software\Wine\AppDefaults\msedgewebview2.exe"
/v Version /t REG_SZ /d win7

In my case with wine-staging 11.17 it also works on win10 since it contains the
dcomp-DCompositionCreateDevice2 patches.

Seems like duplicate of bug 58921, unless it's specific to your nvidia gpu.
