Firefox rounded edges on Sway

Hi there,

I do not really know where to put this but I think sharing it is the right move. 
I am using Sway with an up to date system.
Since last firefox update when I launch it, top corners are rounded for a split second and then become square as intended by the WM.
That may be a bug specific with firefox since i tried other GUI apps and they did not have that issue as well.
But that said, did you encounter something similar ?

Re: Firefox rounded edges on Sway

type about:config in addressbar and look for these 3 settings :

sidebar.revamp.round-content-area
widget.non-native-theme.gtk.scrollbar.round-thumb
widget.non-native-theme.win11.scrollbar.round-track

The top 2 should be true, the last one false .

Try changing the 2nd one to false. If that doesn't help , try the first one and if that also doesn't help try to set both to false.

Re: Firefox rounded edges on Sway

So I tried both disabling only the second and disabling both.
Unfortunately it did not solve that temporary round corner issue.
And weirdly enough, when all 3 are set to false I get "security issue" while trying to reach arch forums like the website has connectivity issues.
So for usability I switched them back to true
