Rendering Fail After Zoom+Scroll

Type: Bug

Reproduction Steps

1. Enable `editor.experimentalGpuAcceleration`.
2. Open a relatively large source file (mine is approximately 700 lines).
3. Use Ctrl + Mouse Wheel to zoom in or out.
4. Scroll through the file repeatedly, changing the zoom level occasionally.
5. After some time, portions of the editor begin rendering incorrectly.

Actual Result

* Large rectangular sections of the editor become completely black.
* Multi-line inline AI suggestions are also affected; instead of rendering the suggested text, a solid black rectangle is drawn over both the suggestion and the underlying code.
* Once the issue starts, the Developer Console is repeatedly flooded with:

* `Attempt to create a texture atlas page past the limit 16`

Expected Result

* The editor should continue rendering correctly regardless of scrolling or zoom level.
* Inline suggestions should render normally.
* No texture atlas errors should be logged.

Additional Information

* Setting `editor.experimentalGpuAcceleration` to **Off** immediately resolves the issue.
* I have not been able to reproduce the problem with GPU acceleration disabled.
* The issue appears to be related to glyph texture atlas exhaustion, based on the repeated "Attempt to create a texture atlas page past the limit 16" errors.
