Description Lukáš Růžička 2018-05-02 08:48:37 UTC
When you try to run Cheese on a computer using an AMD graphic card, the application starts but is unable to create a main window to communicate with users. The problem is described more here https://bugzilla.redhat.com/show_bug.cgi?id=1560481.

It has been identified, that the AMD cards started to support HDR colours that caused some application to behave in a weird way. The problem, in Fedora 28 was workarounded by switching the support off in the Mesa library (mesa-18.0.1-2.fc28).

However, we would like to support these features in Fedora 29 and the applications, such as Cheese, should be ready for this step.
Comment 1 Lukáš Růžička 2018-05-02 09:41:11 UTC
To add some more info to the previous:

* The problem exist probably because of poor support of rgb10, also described here https://gitlab.gnome.org/GNOME/mutter/issues/2.
* According to Jonas Adahl (Comment 26 of the Redhat Bugzilla) this looks like a problem with clutter.
* Comment 33 of the above mentioned suggests a temporary solution, a.k.a. the workaround, which seemed to work and was used for Fedora 28 to make Cheese fixed. 

In one of the meetings, Matthias Clasen stated that: "... the only clutter we care about is the one inside mutter. Anything else using clutter is living on borrowed time."

Therefore I am not filing the bug against clutter but rather against affected applications.

bugzilla.gnome.org is being replaced by gitlab.gnome.org. We are closing all
old bug reports and feature requests in GNOME Bugzilla which have not seen
updates for a long time.

If you still use cheese and if you still see this bug / want this feature in a
recent and currently supported version, then please feel free to report it at
https://gitlab.gnome.org/GNOME/cheese/-/issues/

Thank you for creating this report and we are sorry it could not be implemented
(volunteer workforce and time is quite limited).
