            Bug ID: 110137
           Summary: drirc adaptive sync, vrr, freesync blacklisting
                    documentation
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All

          Priority: medium
         Component: Drivers/Gallium/radeonsi

Hi,

using qutebrowser in fullscreen mode breaks the video output with VRR enabled
because it refreshes very unsteadily, which is typical for a browser. Some
browsers are blacklisted in the drirc. I've added the following lines to the
drirc, but it doesn't disable VRR for a fullscreen qutebrowser window.:


<application name="qutebrowser" executable="qutebrowser">
    <option name="adaptive_sync" value="false" />
</application>


Is there any documentation about how the matching works?

AFAIK, the matching should just be done based on the executable name.

See: src/util/u_process.c

The process name likely differs for the content processes for the browser. You
might need both qutebrowser and QtWebEngineProcess blacklisted:


<application name="qutebrowser" executable="QtWebEngineProcess">
    <option name="adaptive_sync" value="false" />
</application>


<application name="qutebrowser" executable="qutebrowser">
    <option name="adaptive_sync" value="false" />
</application>

Neither qutebrowser nor QtWebEngineProcess worked. Now I've seen that qtbrowser
is built on PyQt5, so the executable name has to be "python3", this works:

<application name="qutebrowser" executable="python3">
    <option name="adaptive_sync" value="false" />
</application>

I'd send in a patch for that, but I think this will block any python3-based
app, which is not the goal here.

I suppose that the issue with using realpath is while it's good at stripping
args from chromium based browsers it'll have issues with programs run under
script interpreters.

Maybe the drirc needs a more advanced app path or name matching method to deal
with cases like that.
