Bug ID: 58491 Summary: Flickering on video-surveilance-app is back Product: Wine Version: 10.12 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: andreas.franz@arcor.de Distribution: ---

Created attachment 78948 --> http://bugs.winehq.org/attachment.cgi?id=78948 started from terminal

Flickering on viewing a camera stream with activated hardware accelerated d3d11 setting is back. Desktop picture and camera picture is swapping. It was gone with 10.0 stable - it's back with 10.12 (maybe some versions earlier).

Software rendering works still fine.

regards, Andy

--- Comment #6 from Rémi Bernon rbernon@codeweavers.com --- Would you mind attaching a log with `WINEDEBUG=+pid,+wgl,+win,+x11drv,+event` environment variable? Thanks!

And of course if you have more detail about the application, if it is publicly available, it will perhaps make debugging easier, and be very much appreciated.

Thanks for your fast response - attached is a logfile while SemSyCompact should display a live-camera with D3D11 renderer.

SemsyCompact is a software for professional Video-Surveilance and is free downloadable: https://www.dallmeier.com/api/1617455215/cloud?action=download&path=/Dow...

--- Comment #8 from AndyF andreas.franz@arcor.de --- - starting the app with winedbg does "nothing" - winedbg shows only a prompt - after quitting winedbg, app starts - starting winedbg without a path and attaching to the pid freezes the GUI of the app.

.. which has the same issue. With software renderer, an standard-MP4 is shown normally. With D3D11 you will see "nothing". So you can test without a real camera-system.
