Render artefact

[DentonTheFox]

I do not know how to describe it, but it catches my eye at the very beginning, I hope you are refining the rendering. My Phone: Redmi 13 Helio G91, Mali-G52

The yellow line is back 😱

Thought I have eliminated it with an earlier build.
I never had this issue. Render refining isn‘t planned.
The line goes away if you switch of the HUD btw and always goes from center to the computer icon.

It could be a GPU driver issue. This only occurs on Mali GPU in my test (R36S with Mali-G31, Onn 4K Plus with Mali-G310 V2). Turning off HUD does hide this artifact, but it also kind of changes gameplay (e.g. difficult to track life and acquired items). If you can look into this issue, it'll be great.

No, It does not. This is not mali gpu driver issue. Mali GPUs strictly follow the OpenGL ES anv Vulkan specifications.
Adreno (and desktop drivers) often "forgive" UB and state violations. When code artifacts on Mali, in 90% of cases it's a bug in the code, which Adreno and Nvdia on desktop simply ignores.
So, it is means gles 2 render was written not followed by strict GL specifications.
It can be fixed by switching to GL Fixed pipeline and using gl4es or ng gl4es by translating gl -> (gles 2.0/gles 3.x). Fewer shaders means fewer bugs and less UB in this broken gles rendering. But using gl4es is not salvation, gl4es has own rendering bugs and UB.

I will take a look at it.

@DentonTheFox and @haojiezhu please can you try the latest build.

Unfortunately, I don't see any changes, if talking about yellow line on portable pc

@DentonTheFox do you have render issues on the UT99 port as well?

I don't see any render artifact in UT99 port on my R36S (RK3326 with Mali-G31) with LineageOS. I will test UT99 port on my Amazon Fire HD tablet and Onn Android TV box later.

Update: UT99 has no noticeable issue on Onn 4K Plus (Amlogic S905X5M with Mali-G310 V2).

@DentonTheFox another try to fix in the latest update, please can you test https://github.com/Andiweli/Unreal-Android/releases/tag/v1.6.0

Nah, I haven't come across it yet

This line doesn't want to come back for me.
