   I assume this is related to https://github.com/bitcoin-core/gui/pull/950, which re-enabled the tests.

   Fixed in https://github.com/bitcoin-core/gui/pull/951

   You can work around it via QT_STYLE_OVERRIDE=fusion for now.

   I am also working on a branch to run test_bitcoin-qt and test_bitcoin from the cross builds in CI, so we have better coverage of some of the binaries being built in these jobs...
