I can confirm a similar fix to snowdrop’s. I get a vertical scrollbar when using a html table that only overlaps horizontally within a q-page. I think this is something to do with Quasar’s implementation of 100vh and scrollbar heights, and I’ve only seen it happen when using tables.
Problem is solved if I wrap my tables in overflow divs:
<div style="position: relative; overflow: auto; max-width: 100%; ">
<table>// Table Content</table>
</div>
By the way I tried all kinds of solutions by altering the q-layouts and q-pages styles but I ran into trouble with transitions and other things. Best off not messing with the quasar layout elements too much.
