Bug ID: 443416
Summary: AppImage deployments lacks OpenGL acceleration due to
xcbglintegrations missing
Product: Craft
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Core
Assignee: vonr...@kde.org
Reporter: javiercorderope...@gmail.com
CC: kde-wind...@kde.org
Target Milestone: ---
SUMMARY
During deployment of Qt gui and opengl modules, deployment of "xcb-gl" fails
because directory /home/$USER/CraftRoot/plugins/xcbglintegrations// doesn't
exist. This results in AppImages lacking the ability to access OpenGL, which
results in lower QML performance, due to lack of graphics acceleration.
STEPS TO REPRODUCE
1. Create a Blueprint for a graphics intensive project
2. Have "dev-utils/linuxdeploy" and "dev-utils/appimagetool" specified in
blueprints as build dependencies for Linux.
> def setDependencies(self):
> self.buildDependencies["dev-utils/linuxdeploy"] = None
> self.buildDependencies["dev-utils/appimagetool"] = None
> # ...
3. On a Linux system, run blueprint: `craft project-name`
4. Then package the project as AppImage: `craft --package project-name`.
5. Test AppImage performance against non-containerized build of project.
OBSERVED RESULT
Graphics intensive project AppImage will result in high CPU consumption and
frame drops during large animations of many seconds.
Packaging process will output:
>[qt/stdout] -- Deploying module: gui --
> [...]
>[qt/stdout] Deploying xcb-gl integrations
>[qt/stdout] Directory /home/$USER/CraftRoot/plugins/xcbglintegrations//
>doesn't exist, skipping deployment
>[qt/stdout]
>[qt/stdout] -- Deploying module: opengl --
>[qt/stdout] Deploying xcb-gl integrations
>[qt/stdout] Directory /home/$USER/CraftRoot/plugins/xcbglintegrations//
>>doesn't exist, skipping deployment
>[qt/stdout]
EXPECTED RESULT
Qt gui and opengl modules deploy correctly. Resulting AppImage has performance
equivalent to its non-containerized counterparts.
