Quad was merged with PlaneMesh. Pick the planemesh from the list and check if it fixes it?
If not, this is likely caused by octahedral compression, probably the single biggest and most problematic change in a15...
Same. I did that just now, and the first time I launched the project, that was my first thought that Quad mesh got merged with Plane mesh, because it was always strange for me to have both and logical to have them merged. But, Plane mesh always had this problem with skewed planes in the viewport when Billboard particle mode turned on in the materials, so I guess when they merged the two, they forgot to fix Plane mesh's Billboard particle mode bug.
To reproduce it do the following:
Here, absolutely new GPUparticles with Plane in the draw pass and new material with Billboard particles mode turned on, it is rendered completely skewed:
The reason why everybody used Quad Mesh in the draw pass was because Plane mesh rendered Billboard particles this way, maybe it got overlooked in gd4alpha14 when the merge happened?
For the QuadMesh/PlaneMesh issue, you need to set the orientation
property of the PlaneMesh to FACE_Z
then it will behave the same as QuadMesh did.
For the other issues, it indeed looks like an Octahedral compression issue. To fix it, you just need to reimport your assets

OMG, thank you for your tip on resolving particle issue, I didn't even see that option there until you mentioned, always used QuadMesh because of that, thank you!

Issue description
I have noticed that particles looked weird in the newest alpha release of Godot 4. At first I thought that it might be the problem with how engine renders mesh with materials that have billboard particles turned on. But then I noticed that in particle mode I don't even have an option to generate quad mesh:
All the GPUparticles that have had Quad mesh assigned in the draw pass, are now automatically substituted with Plane mesh, where Particle Billboard in the material options looks skewed (Should it look like that, or is it also a bug?).
For example, this used to be normal fire particle in Godot alpha 14, now it's broken in Godot alpha 15.
Also, I have noticed that Godot4 alpha 15 permanently breaks compatibility of majority of shaders both visual and spatial and GPUparticles made in Godot4 alpha 14, completely corrupting the project? But that is my assumption so far. I don't know if it is intentional and now I should start everything from scratch in GD4alpha15.
Same scene in Godot4 alpha15 looks like this (previously made in Godot4 a14):
Same project in Godot4 loaded again in Godot4 alpha14:
P.S. The whole project is weird now, even when shader cache is deleted and .godot folder inside the project is wiped.
Steps to reproduce
1 - Add a GPUparticle scene 2 - Go to draw pass tab and look at the list of objects to draw
To reproduce the weirdness with shaders I experience:
1 - open a project with different shaders and GPUparticles made in GD4 alpha 14 with GD5 alpha 15, compare the two differences, it is impossible to not notice problems.
