Video Scopes panel — scale graticule text renders pixelated/low-resolution on M5 MacBook Pro Retina display. Legacy Scopes render correctly. New scopes text is clearly not HiDPI-aware.

Bug: Color Mode HUD waveform scope renders at extremely low point density — M5 MacBook Pro

System: M5 MacBook Pro, macOS Tahoe 26.4.1, Premiere (beta) 26.5.0 build 3, Metal GPU renderer

What's happening: The HUD waveform scope that appears when clicking a Color Mode control (e.g. Contrast) renders at roughly 2–5% of expected point density. Instead of continuous waveform traces, the scope displays a sparse scatter of individual pixels — the underlying data appears correct (sky at ~60–75%, shadows near 0–20%) but the rendering is so low-density the scope is unreadable as a grading tool. The scope background and panel dimensions render at full resolution; only the waveform trace points are affected.

Expected behavior: Dense, continuous waveform traces as shown in Adobe's own Color Mode tutorial videos and documentation screenshots.

Reproduction: Open any clip in Color Mode → click any control that triggers the HUD waveform (Contrast, Exposure, etc.) → HUD appears with sparse pixelated trace instead of dense continuous waveform.

Additional notes: The Video Scopes panel has the same issue on the new Color Mode scopes. Switching to Legacy Scopes (hamburger menu → Show Legacy Scopes) renders correctly at full density. Issue appears to be specific to the new Color Mode scope rendering path on Apple Silicon.

Screenshot attached.
 

Workarounds already attempted (none resolved the issue):

• Playback resolution confirmed at Full
• GPU renderer confirmed as Metal
• Color Monitor panel enlarged to maximum available size
• Display Color Management preference enabled
• Maximum Bit Depth and Maximum Render Quality enabled in Sequence Settings
• Render files deleted and sequence re-rendered
• Video Scopes panel resized larger
• Updated to latest available beta build
• Issue persists across both the HUD overlay and the Video Scopes panel on the new Color Mode scopes
• Legacy Scopes (hamburger menu → Show Legacy Scopes) render correctly, confirming the issue is isolated to the new Color Mode scope rendering path
