Today I pushed a change to KWin which fails on the CI system. My interpretation is that this is due to no icon theme being installed. Is it possible to make an icon theme available to the run tests or should I try to workaround in the tests?
The relevant commit is 5795fc8cc04a422194e06d20fb395cbbf3ea2ad6 and it broke the testInternalWindow and testShellClient (and their waylandonly variants). The test verifies that the "wayland" fallback icon is set and we get back that no icon is set at all. This can only happen if there is no icon theme.
Working around the issue would be simple, but would create differences in running the test locally or on CI.
