Transparency issue in Cinnamon over Arch

[ykonstant1]

I am submitting a Bug Report

Problem or Feature in Brief

I am using the latest arch bundled version of cmatrix (2.0) with Cinnamon DE in Arch. My terminal emulators include Terminator, urxvt, Gnome term and Konsole. They are configured with light yellow tranparent background. When cmatrix runs, it replaces that background with black in all samples. After I exit cmatrix, transparency is restored.

On my Mint system with Cinnamon DE, with the exact same stylistic choices and terminals, cmatrix (v. 1.2 bundled with Ubuntu) correctly respects the transparent terminal background.

It is unclear to me where the bug lies, but since I and another couple of people could not find any help in linux fora, I hope the developer may be able to help.

Edit: Downgrading the package to the 1.2 version fixes the problem. There seems to be something wrong in the transition 1.2 to 2.0 for my system.

Same problem. Using arch linux, black background in kitty terminal with transparency. Fixed by installing cmatrix-git in aur that uses cmatrix 1.2.

same problem in manjaro gnome

Same bug on arch. I'm on i3wm and termite.

Also on Arch. Seeing an opaque background. DE: GNOME and Terminal. Downgrading to cmatrix 1.2 (installing cmatrix-git from AUR).

Same on Konsole and Plasma 5

This is most likely due to an issue in the cmake directive. If the anyone here would like to try building with

autoreconf -i
./configure
make

and let me know the results, it would be appreciated.

@space-pagan Confirmed on Arch Linux, building with make gives the default background color, and with cmake does not.

Also, the difference between aur package and official repo package is exactly the build method they use, see https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=cmatrix-git#n23 https://github.com/archlinux/svntogit-community/blob/ad595eb1c0a7b67f8b8652cd4ad8ca9d0ea5cb1a/trunk/PKGBUILD#L26

Wonderful. I'm working on fixing the cmake to make it behave the same as autotools. Expect a patch soon.

Transparency issue is still present. It work with AUR package, but not official repo package.

Bug is still here, so I've opened a bug track on archlinux : https://bugs.archlinux.org/task/76925
