I’ve encountered an odd behavior with the Colour Contrast Analyser (CCA) (https://github.com/ThePacielloGroup/CCAe) app on my system. I reported this issue in detail to the developers over a year ago with no solution. I have tried both the RPM and AppImage versions.
When I click on the eyedropper tool, nothing seems to happen. I did a screen recording and discovered the following dialog pops up for a fraction of a second (much too quickly to interact with):
I’ve searched, but have not found a reference to this dialog. Does anyone recognize this dialog and know how to configure whatever subsystem this is from to automatically select my primary display?
Here’s an issue report, which I think is the same issue you are experiencing:
The ticket was opened back in March 2025 and seems to be unresolved still. Also, it seems the software is no longer maintained according to the developer:
It seems instead of forking it he decided to create another app from scratch. I know this isn’t an answer to your question, but it seems the app simply doesn’t work and seems unlikely it will be updated in the future.
