Gemini 3.8 Flash Model Regression: Low-quality styling and broken layouts on new project initialization (Web & App)

There has been a severe quality regression in web layout generation when initializing a new project from scratch using Gemini Balanced 3.8 Flash. Previously couple of monthe ago, the model generated modern, cohesive, and high-quality designs. Following recent updates, the layout generation has degraded drastically for brand-new projects.

The model does output CSS, but the styling is extremely primitive and visually broken. Common layout failures include:

  • Overlapping Text: Typography elements crash into each other due to broken line heights or absolute positioning mistakes.
  • Unnecessary Page Breaks / Line Breaks: Random vertical spacing, unintended margins, or layout collapses that disrupt the visual flow.
  • Bare / Unstyled Navigation Bars: Navbars are generated with little-to-no styling, reverting to raw bullet lists or completely unaligned links.

Behavior Across Platforms & Models:

  • Web Option vs App Option: This critical failure happens 100% of the time when selecting the Web option for a new project. If the App option is selected instead, the error still exists but it is intermittent (it only happens sometimes).
  • Model 3.8 Flash vs Speed Model: When switching to the Speed model, the layout outcomes improve slightly and look better than the 3.8 Flash outputs. However, the quality is still significantly inferior compared to the previous version’s standards, which were highly superior.
  • Existing Projects Exception: This issue only occurs during clean project generation from scratch (even when a design.md architecture blueprint is provided). If the model is tasked with modifying or adding features to an existing project that already has established styles, it respects the existing codebase and performs its job perfectly without breaking anything.

Expected Result

The model should generate a polished, modern, and production-ready visual interface, matching the high-quality layout capabilities it possessed prior to recent updates.

Actual Result

The website renders with highly broken, elementary styles, especially under the Web project configuration. Text overlaps, navigation menus lack alignment/padding, and random vertical spacing breaks the page layout, rendering the scratch generation feature unusable without manual heavy refactoring.

Promt:

Design a premium, modern, and visually stunning B2B website for IMPORTRU, a technology solutions company specializing in enterprise IT infrastructure, software licensing, cloud solutions, and data protection.

The website should feature a sophisticated, innovative, and minimalist design inspired by leading enterprise technology companies such as Dell Technologies, Red Hat, HPE, and IBM.

Brand Color Palette:

  • Primary Red: #ED1A37

  • Dark Gray: #303130

  • White: #FFFFFF

  • Accent Red: #DE1E2F

Create four main sections:

1. IT Infrastructure
Showcase enterprise-grade servers, storage systems, networking solutions, virtualization platforms, and data center infrastructure. Use realistic high-quality images of servers, server racks, and modern data centers.

2. Enterprise Software & Licensing
Highlight enterprise software solutions including Red Hat Enterprise Linux, Oracle Linux, Red Hat Ansible Automation Platform, JBoss Enterprise Application Platform, and virtualization technologies. Emphasize scalability, automation, security, and operational efficiency.

3. Cloud Solutions
Present hybrid cloud, private cloud, cloud migration, virtualization, and cloud infrastructure management services. Incorporate modern cloud architecture visuals and elegant diagrams illustrating interconnected IT environments.

4. Data Protection & Cyber Resilience
Focus on enterprise backup, disaster recovery, business continuity, ransomware protection, and secure data storage solutions. Use modern cybersecurity-inspired visuals that communicate reliability, resilience, and trust.

UI/UX Design Requirements:

  • Create an impressive full-width hero section with a compelling headline: “Powering Your Digital Infrastructure.”

  • Use a clean, premium enterprise aesthetic with generous whitespace, strong typography, and sophisticated layouts.

  • Incorporate interactive service cards, subtle animations, hover effects, and smooth transitions.

  • Include modern 3D-inspired technology illustrations, high-quality infrastructure photography, and subtle gradient backgrounds.

  • Use alternating light and dark sections to create visual contrast and hierarchy.

  • Include intuitive navigation, clear service descriptions, and prominent calls to action such as “Explore Solutions”, “Request a Quote”, and “Talk to an Expert”.

  • Design a fully responsive experience for desktop, tablet, and mobile devices.

  • Prioritize accessibility, intuitive navigation, and effortless discovery of solutions.

Overall Objective:

Create a distinctive, high-end enterprise technology website that communicates innovation, reliability, technical expertise, and business value.

The design should feel like a premium technology consulting and infrastructure solutions provider, not a generic e-commerce store.

Every section should educate potential B2B customers, communicate the benefits of each technology, and guide visitors toward requesting a consultation or quotation.

Important: All visible website content, including headlines, descriptions, navigation labels, and buttons, must be written in professional Latin American Spanish.
