black boxes instead of buttons

[tpapp]

I get black boxes instead of buttons, both with master and 1.0-1 in Ubuntu 21.04.

I am using intel-media-va-driver-non-free:amd64 21.1.1+ds1-1 (cf #267)

Happy to compile experimental branches and provide more debugging info.

hi, thanks for the report! Can you check if the svg plugins for Qt are installed? I'm not sure which packages exactly but libqt5svg5 or libqt5svg5-dev maybe

[tpapp]

Yes, both are installed.

Can you please also check the following list: qt5-default qtdeclarative5-dev qtmultimedia5-dev qml-module-qtquick-controls libqt5svg5-dev libqt5xmlpatterns5-dev libqt5sensors5-dev qml-module-qtquick-particles2 qttools5-dev-tools qml-module-qtmultimedia libqt5multimedia5-plugins

If not, are there any issues in the console when running GCompris from command-line? Still if not, can you check if the same appears using the version in https://gcompris.net/downloads-en.html#linux?

All of those are installed:

except for qt5-default which is probably obsolete:

Package qt5-default is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

To confirm gcompris-data is also installed?

Are there any issues in the console log when running GCompris from command-line? Still if not, can you check if the same appears using the version in https://gcompris.net/downloads-en.html#linux?

[tpapp]

gcompris-qt-data is installed. The console log is

I am in the process of checking the same thing with the binary you linked above, but the download is very slow and it will take some time.

[petitlapin]

Ok so the issue is "QSGTextureAtlas: texture atlas allocation failed, code=501".

Can you check if you have libqt5quick5-gles? If yes, can you remove it and install libqt5quick5 instead (idea from https://ubuntuforums.org/showthread.php?t=2442842)

[petitlapin]

other workaround if the previous one does not work: https://bugreports.qt.io/browse/QTBUG-58585 (but the fix from the previous answer is cleaner): MESA_EXTENSION_OVERRIDE="-GL_EXT_bgra -GL_EXT_texture_format_BGRA8888" gcompris-qt

[tpapp]

@petitlapin: using libqt5quick5 fixes the issue, for the Ubuntu binary, the binary you linked above, and master.

The Debian bug report suggests that this should be fixed in upstream, so we just have to wait for it to trickle through the next release.

Thanks for helping me investigate this.
