[ARM64] UI Text Rendering Issues; Skybox Flickering; In-game Intro is Green

Description of Issue I followed installation instructions from the How to build and setup on Linux page, and checked for correct dependencies. After compiling, I build a native package and installed it, copying game files to the specified directory. Upon launching the game, all text is garbled and warped, barely legible, while some lines are completely unreadable.

When launching into the game, the intro is solid green, and remains until gameplay has started. Text in the HUD is warped and spans the screen on occasion. The skybox flickers and twists around while moving, and when standing still it usually corrects itself after a second. Other than these two major distractions, all 3D objects, terrain, game logic and sound seem to be working as intended.

Steps to reproduce

1. Compile xray-16 using 'gcc' with parameters: CFLAGS="-march=native" CXXFLAGS="-march=native" cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_BINDIR=/usr/games
2. Run make package, install with dpkg -i openxray_*_arm64.deb
3. Copy game content from a Windows install into: "~/.local/share/GSC Game World/S.T.A.L.K.E.R. - Call of Pripyat"
4. Run game from terminal: xr_3da
5. Menu text is barely legible, start a New Game, select Rookie, then wait for game to load.
6. Upon starting game, Intro cut-scene is "solid green" until player is loaded.
7. UI text is illegible and spans the screen, skybox flickers constantly. There are no issues with 3D objects, sounds, or gameplay.

Expected behavior All text to be properly rendered throughout the main menus and game HUD. In-game world skybox should be static in appearance to the player. Intro FMV should show video/slide, audio works correctly however.
