Menu button text renders blurry/garbled during play, no consistent trigger

Summary:
Text on buttons in various in-game menus (Settings, World Select/Edit, Save & Quit confirmation) renders blurry and garbled instead of clean and readable. Gameplay itself is unaffected, only menu/button text is affected.

Steps to reproduce:
Launch Minecraft Bedrock and play a world. Open Settings, or the world select screen, or the Save & Quit confirmation dialog. Button text appears blurry and garbled rather than sharp.

Expected result: Menu button text displays sharp and readable.
Actual result: Text is blurry and garbled.

Additional notes:
Fully closing and relaunching the game clears it every time. A full app data reset (via Windows Settings > Apps) also cleared it once, but the issue returned after continued play. Graphics driver is fully up to date (Intel UHD Graphics 630, driver 31.0.101.2145), issue persists regardless. Monitor refresh rate is 59.94Hz, not a high refresh rate. No consistent pattern to when it happens, has occurred within 10 minutes of starting a session, and has not occurred during 6+ hour sessions. Actual game version at time of report is v26.52.
