Some Davinci Resolve floating windows close after moving mouse, unless...

unless said window opens under the cursor. it will close when you move your mouse over the main app.

also these windows have an annoyingly big blurry margin around them, which i couldn't turn off

compared to other floats:

I ran into the exact same issue, and after some testing I found a reliable workaround using window rules:

# Davinci Resolve pop-ups (e.g. "Change Clip Duration")
windowrulev2 = tag +drpopup, class:^(resolve)$, floating:1

# Prevent Resolve from closing the popup on mouse movement / pointer leave
windowrulev2 = stayfocused, tag:drpopup

# Remove XWayland transparent margins (fixes annoying blurry borders)
windowrulev2 = bordersize 0, tag:drpopup
windowrulev2 = noborder,    tag:drpopup
windowrulev2 = noshadow,    tag:drpopup
windowrulev2 = rounding 0,  tag:drpopup
windowrulev2 = opaque,      tag:drpopup

Add this at the end of your ~/.config/hypr/hyprland.conf or whatever config for your window rules.

The problem is that Davinci Resolve is not Wayland-friendly and therefore Hyprland interprets it's pop-ups wrongly.

This fixes:

• Popups instantly closing when moving the mouse or clicking outside
• Blurry / semi-transparent border around popups (XWayland artifact)

this is exactly the fix i needed. thanks for the help!
