GDK_SCALE=2 in my
.xinitrc to deal with HiDPI and it seems that 1Password has started ignoring this and opens the application zoomed in (2X or 4X I'm not sure). If I invoke 1password with
GDK_DPI_SCALE=1 GDK_SCALE=1 1password the problem goes away.
I'm not sure if 1Password has any Chromium inside it but Chromium introduced a bug recently that had similar effects and while they have fixed in their newer revisions it percolated to some other chromium-based applications (e.g. Brave and Slack). Given that 1Password did not have this issue before maybe they're related?
I'm using i3 on Xorg with the following relevant bits in my
xrandr --output DP-0 --mode 3840x2160 --pos 0x0 --primary --scale 1.3x1.3 export GDK_SCALE=2 export GDK_DPI_SCALE=0.5
