When I install Manjaro KDE at first Chromium works fine but after a few rounds of updates the browser takes over 20 seconds to start up while before that it starts up in 1-2 seconds. When it starts up you see an icon appear in the taskbar (panel), then the icons disappears and over 20 seconds later the browser finally opens. This is not only with the browser Chromium, it also applies to any browser which uses the engine Chromium, including Brave, Opera and Vivaldi.
After this happened I tried to remove the chromium-folder in ~/.config, that did not help. I had Chromium start up with a flag: “chromium --password-store=basic”. It worked fine after that, only after updates it broke and on a previous installation when I didn’t use the flag it also broke.
The logical questions. Is it known what causes this problem? If not, how can we find the cause?
