Does anyone else get an AMD GPU driver crash when viewing shadows using PSSM 4 Splits or PSSM 2 Splits in DirectionalLight3D in Godot 4.4 betas/RC? I've tested the exact same scene in 4.3, and it does not crash.
Orthogonal shadows do NOT cause a crash in 4.4, so I'm wondering if something changed regarding PSSM shadows between 4.3 and 4.4.

^v4.4.rc1.official [8ed125b42] (where it cuts is the crash)
^v4.3.stable.official [77dcf97d8] does not crash

Report on the official github, what you've provided here is enough information. https://github.com/godotengine/godot/issues
spring sierra
Yes, please report that.
As for what may have changed, only a few PRs mention PSSM: https://github.com/godotengine/godot/pulls?q=is%3Apr+pssm+is%3Aclosed+milestone%3A4.4
But it's quite possible something else changed, or serching directly for "PSSM" is too narrow
If you have time, it would be helpful to test intermediate releases between 4.3 and 4.4beta1, to isolate exactly which dev version introduced the regression. This will make it easier to bisect to the exact commit which introduced the regression

I am about to report it on the github. Just have to record a few more things
^v4.4.rc2.official [01545c995] (once again crashes where the cut is)
^v4.4.dev1.official [28a72fa43] does NOT crash
dev5 doesnt crash
dev7 doesnt crash
beta1 doesnt crash
beta4 DOES crash
beta3 DOES crash
beta2 DOES crash
ok so I found the real issue
^when you use that button it makes PSSM shadows crash your AMD GPU driver
^ using this makes 4.4rc2 not crash
^v4.4.rc2.official [01545c995] NOT crashing once "Keep the aspect ratio of the embedded game." is selected.
