Basically the framebuffer size was different from the glViewport size.
This made the depth read in glReadPixel not corresponding to the center of the pixel.
Another thing that reduced precision compared to blender 2.79 is the `GPU_matrix_unproject` that now computes using `float`s instead of `double`s.
But this may be for another commit.
There was missing flush from transform update to the point cache
reset. Caused by the fact that when update happens in the "middle"
of component all the component operations will be tagged for update
(since the intermediate state is not stored), but that will not
flush updates to other operations since that would cause too much
of updates.
This now we tag point cache for reset after evaluation operation
but before final transform and before rigid body world.
Due to recent changes the AA was not rendered in the viewport when not
interacting. When interacting it was. This was due to incorrect
detemination to perform TAA.
This was inherited from 2.7x behavior with groups, but in 2.8
collections are also used as 2.7x layers, which turns to be a problem
when pasting back clipboard content, since it would instantiate
collections instead of objects, quickly leading to tens of new
collections in the viewlayer...
Instead, we only copy selected objects from the 3DView now. On paste
time, those will be added to the active collection.
Last part of fixes related to T61670.
Mouse wheel on menus changes the selected item item which doesn't work
well for popovers since buttons aren't always stacked vertically.
Resolves T62777
Create a new pass for them and draw them separately.
Beware of the double multisample resolve when multi-editing a mix of curves
with and without the "in front" option enabled.
The issue is a feedback loop with point cache reset operation.
Solved by introducing extra node which ensures object's transformation
is ready for simulator input. Allows to route relations without causing
a fake dependency cycle now.
This patch adds a new "Use Alpha" option on image empties to avoid ordering
issue of reference images.
If ordering is not important, "Use Alpha" can be enabled to provide
transparency and alpha blending support.
The issue was caused by mesh needed for dynamic paint brush being
stored in the modifier. That make it to be freed and set to NULL
when running copy-on-write.
Solved by moving the mesh to be stored in modifier's runtime data.
