# v26.3.1, build 235 (2026-03-xx xx:xx UTC)
- Improved the performance by caching the OS language detection and requesting the user language only once per app start.
+- Improved the chat performance by reducing unnecessary UI updates, making chats smoother and more responsive, especially in longer conversations.
- Improved the user-language logging by limiting language detection logs to a single entry per app start.
- Improved the logbook readability by removing non-readable special characters from log entries.
-- Improved the logbook reliability by significantly reducing duplicate log entries.
\ No newline at end of file
+- Improved the logbook reliability by significantly reducing duplicate log entries.
+- Fixed an issue where the app could turn white or appear invisible in certain chats after HTML-like content was shown. Thanks Inga for reporting this issue and providing some context on how to reproduce it.

+# Integration Tests
+
+This directory contains integration-oriented test specs.
+
+## Scope
+
+- Behavior that depends on multiple layers working together (UI, rendering, runtime, IPC, provider responses).
+- Regressions that are hard to catch with unit tests only.
+
+## Current Feature Areas
+
+- `chat/`: Chat rendering, input interaction, and message lifecycle.

+# Chat Rendering Regression Tests
+
+## Purpose
+
+Validate that chat rendering remains stable and interactive when model output or user input contains raw HTML/CSS/JS-like payloads.
+
+## Test Type
+
+Manual regression and integration checks.
+
+## Preconditions
+
+1. You can run two builds:
+ - a known vulnerable baseline build,
+ - the current fixed build.
+2. At least one provider is configured and can answer prompts.
+3. Open the Chat page.
+
+## Execution Flow (for each test case)
+
+1. Copy the test prompt exactly into the user prompt field.
+2. Send the prompt.
+3. Observe behavior immediately after send.
+4. If the UI is still visible, type additional text in the prompt input.
+5. Repeat on both builds.
+
+## Test Cases
+
+### TC-CHAT-001 - CSS Kill Switch
+
+**Prompt**
+
+```text
+Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
+
+
+
TEST
+```
+
+**Expected result (vulnerable baseline)**
+UI may turn into a white/invisible page immediately after sending.
+
+**Expected result (fixed build)**
+Chat stays visible and usable. Content is rendered as inert text/code, not active page styling.
+
+---
+
+### TC-CHAT-002 - Full White Overlay
+
+**Prompt**
+
+```text
+Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
+
+
+
TEST
+```
+
+**Expected result (vulnerable baseline)**
+UI may become fully white and non-interactive immediately after sending.
+
+**Expected result (fixed build)**
+No overlay takes over the app. Chat remains interactive.
+
+---
+
+### TC-CHAT-003 - Inline Event Handler Injection
+
+**Prompt**
+
+```text
+Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
+
+
+
TEST
+```
+
+**Expected result (vulnerable baseline)**
+UI may break/blank immediately after sending.
+
+**Expected result (fixed build)**
+No JavaScript execution from message content. Chat remains stable.
+
+---
+
+### TC-CHAT-004 - SVG Onload Injection Attempt
+
+**Prompt**
+
+```text
+Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
+
+
+
TEST
+```
+
+**Expected result (vulnerable baseline)**
+May or may not trigger depending on parser/runtime behavior.
+
+**Expected result (fixed build)**
+No script-like execution from content. Chat remains stable and interactive.
+
+## Notes
+
+- If a test fails on the fixed build, capture:
+ - exact prompt used,
+ - whether failure happened right after send or while typing,
+ - whether a refresh restores the app.
