Having really odd memory issues with shaders enabled
I'm having a really bizarre issue with iris, and I've been trying to find the cause of this issue for a week.
When I have iris disabled, my RAM usage sits around ~13 GB, even when in creative and generating new chunks. However, if I enable shaders, after a few minutes my RAM usage continually rises until I disable shaders. I've found some github issues that are similar to what I am experiencing:
https://github.com/IrisShaders/Iris/issues/1862
https://github.com/IrisShaders/Iris/issues/1862
My GPU temps are ~50C, it's not an overheat issue. VRAM hovers around 80%, so it's not my GPU running out of VRAM.
This issue does not occur if I have iris disabled, it only happens when I have shaders enabled. I've tried using different shaders, that did not help. Completely out of ideas here.
Technical info:
MC version -
1.19.2
(cannot upgrade, most mods in the ecosystem are still on 1.19.2)
Iris version - 1.4.5
Sodium version - 0.4.4
Loader - Fabric
GPU : Nvidia RTX 2060

FPS starts dropping when using shaders for a certain amount of time...
What happened? After a period of playing with shaders, my fps starts to drop constantly creating instability, becoming unplayable, restarting seems to "solve" the problem temporarily, but...

ok first of all
you are on a ridiculously old iris version @Noble_Draconian
i'm... not sure how you expected any support?
I can't update it because 1.6.x breaks with immersive portals
And the mod author for immersive portals stated they are no longer supporting 1.19.2, despite a majority of mods being on that version
Ended up ditching immersive portals as it was causing too much server instability. Upgraded to iris @ latest and the memory leak is gone, seems one of the updates addressed the issue
