Description Adam Sjøgren 2018-01-27 15:34:22 UTC

Upgrading from 1.19.5 to 1.19.6 on my Debian unstable laptop (Intel
graphics), the borders that XMonad (0.13) draws around RGBA-windows,
such as the terminal emulator Sakura¹, have become transparent.

There used to be a bug in XMonad causing the same problem (fixed in
0.13) - this time it seems to be a regression in X.org² - or maybe
XMonad needs to be fixed in a different way?

In any case, downgrading to 1.19.5 fixes the border.

On a suggestion from the Debian developer Timo Aaltonen, I tried
removing the patch 07-glx-do-not-pick-srgb-config-for-32bit-rgba-visual.diff
(related to bug #103699), but the problem persists.

This seems to indicate that either I failed to remove the patch
properly when rebuilding the package, or the problem is due to another
change in 1.19.6.

Let me know if there is something I can do to debug further.

Comment 1 Adam Sjøgren 2018-01-27 15:56:09 UTC

It is sufficient to downgrade the xserver-xorg-core package in Debian to 1.19.5 to restore the non-transparent borders.

The package contains these .so's:

 /usr/lib/xorg/modules/drivers/modesetting_drv.so
 /usr/lib/xorg/modules/extensions
 /usr/lib/xorg/modules/extensions/libglx.so
 /usr/lib/xorg/modules/libexa.so
 /usr/lib/xorg/modules/libfb.so
 /usr/lib/xorg/modules/libfbdevhw.so
 /usr/lib/xorg/modules/libglamoregl.so
 /usr/lib/xorg/modules/libint10.so
 /usr/lib/xorg/modules/libshadow.so
 /usr/lib/xorg/modules/libshadowfb.so
 /usr/lib/xorg/modules/libvbe.so
 /usr/lib/xorg/modules/libvgahw.so
 /usr/lib/xorg/modules/libwfb.so

This patch (comment:10) does not fix the transparent border problem for me (I added the patch using quilt, rebuilt the .deb package and installed it).

After this, I tried reverting 91c42093 "glx: Duplicate relevant fbconfigs for compositing visuals" entirely, and that made the problem go away.

I did, however, suspect I failed to apply the patch from 104597#c10 correctly, so I tried again - but the result was identical, it does not fix the problem for me.

Comment 5 Adam Sjøgren 2018-05-26 09:54:15 UTC

I just got Xorg 1.20.0 installed, as it has been added to Debian unstable, and this problem persists: running Xmonad 0.13 the borders around RGBA windows, such as the terminal emulator Sakura, are transparent.

I will try building 1.20.0 with 91c42093 "glx: Duplicate relevant fbconfigs for compositing visuals" reverted, as I did for 1.19.6.
