Random render artefacts on Windows
hhoushiar last edited by
So I am developing a software with Qt Quick that does pointcloud rendering.
I have some rendering code which uses the old Fixed Function Pipeline methods (can't really change this).
I am trying to create my rendering code as an Qt Quick item that I can add to my project like any other QML element.
And to achieve my goal I am using QQuickFramebufferObject and QQuickFramebufferObject::Renderer.
It works fine on all platforms (Windows, Linux, MacOS).
Have to mention that I am using Qt 5.9.
I recently deployed the software after testing it on all mentioned platforms in the office and I got an email from a customer including these images and asking what is happening with the visualization:
The pointcloud and all the old Fixed Function Pipeline visualization works just fine on their system only the Qt elements have these random render artefacts.
I really don't know what is the issue and since I can't recreate the problem on the machines that I am using for testing I don't know how I can figure out the problem.
So has anyone encountered a similar issue?
Or Do you have any suggestion on what could be the cause of this problem?
I would appreciate any help.
Try it out on machine with no OpenGL drivers installed - maybe they have issue with MESA or the DX12 renderers?
