Bug ID: 386142
Summary: Touch docker (or any QML-based dockers) requires
working OpenGL implementation
Product: krita
Version: git master
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Dockers
Assignee: krita-bugs-n...@kde.org
Reporter: alvinhoc...@gmail.com
Target Milestone: ---
This is kind of niche because I think this can only happen on Windows 7 when
the graphics driver isn't installed or when running over rdp.
For some reason the software D3D renderer used via ANGLE just refuses to work
under Windows 7, so the main window can't be composited at all when the touch
docker is enabled.
A solution is to bundle the `opengl32sw.dll` Gallium llvmpipe driver that comes
with official releases of Qt
(https://download.qt.io/development_releases/prebuilt/llvmpipe/windows/), but
then it will need to be handled from the Windows OpenGL handling code in
addition to the existing desktop OpenGL and ANGLE handling, which will make the
code even more complex. Also means additional packaging steps.
