Known issues and limitations
High DPI support on Windows is disabled by default due to known instabilities with QtWebEngineWidgets in Qt 6.5.3 on Windows which are used by Flow Production Tracking packages. You can still activate High DPI on Windows by setting the “RV_QT_HDPI_SUPPORT” environment variable but we cannot guarantee the results. [SG-40030]
The new High DPI displays support in RV can also be disabled by setting the “RV_NO_QT_HDPI_SUPPORT” environment variable if you encounter any issues with custom RV packages, for example.
If RV isnt authenticated, when we try to open a quicktime from CLI, RV will just hard Crash.
Here are 2 seperate steps to reproduce the issue.
A. Open h264 media through CLI
Clear your authentication cache (~.rv, ~./config/TweakSoftware, ~/.local/share/TweakSoftware)
Open your h264 media through CLI (/opt/RV/bin/rv /my/file.mov)
RV will sloly open and then crash
B. Set RV to be your default media player in Maya
Open Maya Preference, set Quicktime Viewing Application: /opt/RV/bin/rvpush-tag playblast merge %f
Do a simple quicktime playblast (encoding jpeg)
RV will slowly open and then crash
The expected behaviour
Let the user authenticate. From my understanding, ffmpeg libraries are loaded after the authentication process, thus crashing if not logged in.
This is reaaally annoying for our Animators since RV is our default media player.
In both cases, here are my error logs when it’s occuring.

We were not having this issue on RV 2023.0.1 (what we used before using 2025.0.0)
Like @pixelconductor however, Screening Room for RV is not remembering any of our custom fields or pages with this version. This is a big issue for our artists, which made us rollback to the previous 2024.2.0 release.
I believe the issue is due to the default QT WebView profile which is now “off-the-record” by default in QT6 (meaning the cookies with the preferences are not saved between instances). CF This QT page. I tried editing the shotgrid_review_app.mu file to make the views in the _webViews attribute use an explicit profile without luck (it seems the stock QWebEngineView() constructor keeps getting called despite my modifications).
I did manage to replace the profiles used in the views, the problem now is that apparently modern chromium versions in Qt6 do not allow redirections to local files when cookies are enabled? I’m struggling to find reliable information about the change, this might be a gemini hallucination, but essentially as soon as I enable cookies, the webview errors with an ERR_UNSAFE_REDIRECT when accessing **https://genesis.shotgunstudio.com/user/redirect_with_local_fallback?url=XXX&fallback=XXX
Edit:
Removing the redirect, and directly accessing the final URL made things work, sometimes requiring me to login directly in the webview, which isn’t really a problem for me.**
Maybe someone from Autodesk is watching this thread, maybe not, but it seems like as of this morning, the saving of favorites and fields has possibly moved server-side rather than relying on cookies?
We had all of our favorites and settings disappear studio-wide, but now it works in RV 2025, and seems to stick around from session to session, even without any apparent cookie saving.
It was a change to the way Qt saves persistent data using its WebEngine that broke this.
Screening room works by downloading javascript code served to it from an FPT server, and we made a fix to that code to solve the issue with the Qt’s persistent directories.
Since RV executes the JS code locally using its QtWebEngine, no changes have been made to how or where they are saved, only the code that does the saving has been modified to account for the new Qt version in RV 2025. Since that fix was deployed this morning, that’s why it started working again for you.
Hi Nelsonr.
First of all, thank you for looking into this issue.
Can you confirm where the data is now saved? It used to be under C:\Users\eleroy\AppData\Local\TweakSoftware\RV in my case, if I deleted the QWebEngine’s cache it would clear favorites and settings. Today I can delete this entire folder and the favs and settings stick around, which was what made me wonder if maybe it had been moved server-side (although logging in on another machine made me realize that’s not the case, wishful thinking).
I can also tell the change is not in the RV package as I’m running my own branch.
Cheers
When you save it will now invoke RV’s commands.writeSetting method. By default on Windows this in indeed HKEY_CURRENT_USER\Software\Tweak Software\RV, but you can technically set that to whatever you want.
You can delete the web engine cache if you so desire and it will not impact your favourites.
