Expected Behavior

Right-clicking in the DevTools preview should be sent and handled by the browser source gracefully.

Current Behavior

Right-clicking in the DevTools preview crashes OBS.

Steps to Reproduce

1. Set OBS launch option --remote-debugging-port=9222
2. Launch OBS
3. Create an empty scene
4. Create a default browser source and OK it.
5. Open localhost:9222 in a browser
6. Select "OBS | Browser Source"
7. Right-click in the preview

OBS should crash at this point.

Anything else we should know?

I've moved this to the obs-browser repo, but I can confirm this crash occurs in OBS 27.1.3.

[RytoEX]

Are either this or #321 reproducible with cefclient for CEF 3770 with the appropriate flags?

[WizardCM]

This is reproducible in cefclient 3770 (75) with cefclient.exe --off-screen-rendering-enabled --remote-debugging-port=9123, but not in cefclient 4430 (90) and 4606 (94), and therefore I'll revisit this bug when we update CEF in OBS on Windows.

[WizardCM]

Confirmed this issue is fixed when updating CEF in OBS to CEF 4638 (Chromium 95). I will close this issue once we merge #323
