I’d prefer not to open a new topic whenever I need to come back to this issue, but the last one has been automatically closed since. Maybe @dae or somebody else can combine the topics, also including the original one?
Please report any improvements or regressions you notice, as we need to decide whether to (partially) revert this before the stable release.
so I can report that the tooltips in Anki 23.10.1rc1 are fine and legible. The problem still occured in 23.10, but no longer in the latest RC.
