Linux: Full screen video Amazon & Hulu both hang

I’m not sure which update caused this to happen, but I’m unable to watch streaming video in full screen mode.

OS: Linux Mint 18.3 Sylvia
Brave: Version 1.15.75 Chromium: 86.0.4240.99 (Official Build) (64-bit)

I can workaround this by killing the Brave GPU process.

Example:

/opt/brave.com/brave/brave --type=gpu-process --field-trial-handle=12135364501604129084,9652919939289643638,131072 --enable-features=AutoupgradeMixedContent,DnsOverHttps,LegacyTLSEnforced,MixedContentSiteSetting,OmniboxContextMenuShowFullUrls,PassiveMixedContentWarning,PasswordImport,PrefetchPrivacyChanges,ReducedReferrerGranularity,WebUIDarkMode --disable-features=AllowPopupsDuringPageUnload,AutofillEnableAccountWalletStorage,AutofillServerCommunication,NotificationTriggers,PasswordCheck,PrivacySettingsRedesign,SafeBrowsingEnhancedProtection,SmsReceiver,TabHoverCards,TextFragmentAnchor,VideoPlaybackQuality --gpu-preferences=MAAAAAAAAAAgAAAQAAAAAAAAAAAAAAAAAABgAAAAAAAQAAAAAAAAAAAAAAAAAAAACAAAAAAAAAA= --shared-files

If I kill this while Brave is running, then things work OK.

Other data point: Most recent Chrome behaves similarly
