https://bugs.winehq.org/show_bug.cgi?id=53074 --- Comment #3 from Flaviu Tamas <winebz(a)flaviutamas.com> --- Linux 5.17.5-arch1-1 x86_64 Nothing interesting in dmesg when the error occurs. This was tested using a "UVC 1.00 device Logitech Webcam C925e (046d:085b)". I also have a cheap webcam, "UVC 1.00 device DEPSTECH webcam (0c45:636b)", which exhibits the same behavior. I also just tested both these webcams using cheese & firefox (one webcam and one client at a time) and all combinations work fine there. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
