Tilix Background Transparency

[Dwayne Hinterlang]

Updated the system and now tilix background is 100% transparent.

Developer Options - Pre-Release (proposed bionic) is enabled.

enc is a git format-patch from the upstream tilix project that resolves this issue - I have added the DEP3 header.

 - https://github.com/gnunn1/tilix/commit/3a7d8e0d31eba62e4bbef0f68006ea28e2a93a0d

The issue occurs because Tilix v1.7.5 is using an API that was originally available in vte2.91 before the beta release.

The beta release of vte that is now in bionic-proposed has removed this API call. It was fixed in the upstream Tilix project but I understand that a formal release of Tilix will not be made until approx 14th March.

If Ubuntu intend to take this newer version then great. If not, this patch should be applied.

This has been tested by enabling bionic-proposed, installing the vte libraries and the latest tilix. Confirmed the transparent observation.

Then pull-lp-source tilix and applied the patch to debian/patches before debuild -us -uc and installing the resulting .deb's that were created.

@jbicha - subscribed your goodself. Please can you sponsor this?

[Jeremy Bícha (jbicha)]

fossfreedom, please subscribe ubuntu-sponsors in the future. In case I'm not available, you won't lose your position in the queue. :)

Have you built this in a PPA? Does the resulting binary hard depend on vte 0.51+? Does the binary have any problems if it's used with vte 0.50?

[fossfreedom (fossfreedom)]

okey-dokey - sponsors - understood!

In terms of a PPA - yes I built tilix (pull-lp-source tilix) with the patch in a PPA which had the proposed repo enabled.

I had to enable the proposed repo in bionic to install due to the phobos library change. This didnt install the revised vte. So yes - the patched tilix worked fine with vte 0.50.

Once I instablled the two vte 0.51 libraries from proposed, again tilix did not exhibit the transparent behaviour. So good news!

[Jeremy Bícha (jbicha)]

I added block-proposed so that the new vte won't accidentally migrate before tilix. tilix would be stuck because of the incomplete ldc transition but vte wouldn't be.

[Jeremy Bícha (jbicha)]

Removing block-proposed since it looks like the ldc transition will finish before vte2.91 will migrate.

Thanks again! I have uploaded this and therefore I'm unsubscribing ubuntu-sponsors. Feel free to re-subscribe if you have something else that needs sponsoring.

This bug was fixed in the package tilix - 1.7.5-2ubuntu2

---------------
tilix (1.7.5-2ubuntu2) bionic; urgency=medium

  * Cherry-pick fix-transparency.patch for compatibility with
    vte2.91 0.51+ (LP: #1750322)
