--- Comment #3 from Sergio <sergio.calleg...@gmail.com> --- Thanks for keeping the bug open for some time. At this point, I do not know if other applications are affected. In case I find some, I'll report on it. Firefox may be a bit special in what it does, since the buttons are meant to cause some graphical overlays to open right below them. My seeing kwin as a suspect comes from these considerations: - Disabling compositing makes firefox behave correctly. With compositing, all the overlay windows/dialogs stop opening (you just see the button appearing as pressed for operations that involve buttons). Also dialogs such as confirmation actions (e.g. for installing extensions) stop appearing. - It is not something related to the firefox profile. Resetting the profile makes no difference. - It is not something related to the specific graphics card. Two machines, one with Intel and the other with NVIDIA seem affected. - It is not something related to the specific firefox version. Tried both 56 and 57 beta and both have the issue. Furthermore, the issue started appearing after I had used FF 56 successfully. - It is not something related to some obscure configuration from the user. I have created a new user on the machine and the issue is also present. - It is not something related to the ubuntu build of firefox. The issue is also present with the generic firefox binary for linux from mozilla. - The issue is also present running firefox with LIBGL_ALWAYS_SOFTWARE=1 Is there anything that you can suggest for confirming or excluding relation with kwin? -- You are receiving this mail because: You are watching all bug changes.
