Bug or Regression?

Bug

Description

Firstly I am not sure if this is a Hyprland bug or a more general Wayland bug or caused by something else. But I know I did not experience this on i3 or xfce on X11.

I have noticed that certain GTK popups render with a transparent background in Hyprland. So far, I have only seen this happen for the Libreoffice popups prompting you to save in an open source file format instead of .doc(x) or .ppt(x), and the final popup window when importing a private PGP key in Thunderbird.

How to reproduce

Libreoffice

Install libreoffice-still 7.6.5-2 from the Arch repos (possibly works on other Libreoffice packages or building from source, but I've not checked—I have used this same package (but possibly a lower version) in X11 and not had this issue).

Open any .doc, .docx, .ppt, .pptx, etc. Attempt to save. Observe a transparent background in the popup.

Thunderbird

Install thunderbird 115.8.1-1 from the Arch repos (again, possibly an issue in other Thunderbird packages or building from source, but I've only used this package). Log in with an email address.

Go to Tools > OpenPGP Key Manager and import a private PGP key for one of your email addresses. Follow the instructions, accepting it as a personal key, and on the final screen (screenshot attached below), the bottom of the window is transparent.

Crash reports, logs, images, videos

Note that in the below screenshots, the appearance of the background is expected behaviour for transparent backgrounds due to my blur settings, however the backgrounds are not expected to be transparent in the first place.

I experienced this stuff in older versions, but don't see it for a while. Probably old version issue. Can you update and check, if it fixed for you?

[revsuine]

Switched to libreoffice-fresh 24.2.1-3 and tried again. Same issue I'm afraid.

Thunderbird is up to date with the latest Arch package.

[Ligthiago]

No, I mean update Hyprland. 0.35.0 is kinda outdated

[revsuine]

Ah ok. I'm on the hyprland package, I'm aware it's out of date but I heard the git version on the AUR was also frequently broken so I've just been using the official Arch package. But I'll try later today with the AUR git package.

this is not a hyprland issue

i have the same problem, its not a GTK theme problem, as the popups show just fine on other X11 sessions, it does seem like a hyprland issue (im on version 38.1-1 arch)

[vaxerski]

what about other wayland sessions...

[M4rti21]

what about other wayland sessions...

just tried it in sway, didnt happent there, i even tried with different gtk themes and the issue persisted on across themes (on hyprland)

my system: Arch linux 6.8.4 hyprland: 38.1 (non git) nvidia propietary: 550.67

themes i tried this with: Colloid-Dark se98-wm-theme

(edit) just checked with Adwaita/Adwaita-dark and issue doesnt happen there... im confused.... those themes did work fine on sway but not on hyprland im guessing those themes are doing something wierd? is there a way for me to set a window rule for "popups" to have no opacity on hyprland?

[vaxerski]

forcergbx but I don't recommend that, rather fix your theme :P

[M4rti21]

ok tyty :D
