Hey there, sorry to hear you're stuck with these frustrating display bugs in CodeLite 12.0.2! It’s weird that core features like compiling and running projects work fine, but the editor and settings dialogs refuse to render any text at all. Since restarts and reinstalls didn’t help, let’s dive into some targeted fixes:

Possible Solutions to Try #

• Update Graphics Drivers & Repair DirectX
  CodeLite uses wxWidgets for its UI, which relies heavily on your system’s graphics components. Older Windows 7 GPU drivers might clash with the rendering engine in CodeLite 12.0.2:

  • Head to your GPU manufacturer’s website (NVIDIA, AMD, or Intel) and download the latest driver version compatible with Windows 7.
  • Run dxdiag via the Win+R Run dialog to check for DirectX errors. If any are found, use Microsoft’s official DirectX End-User Runtime installer to repair your system’s DirectX setup.

• Reset Corrupted CodeLite Configuration Files
  Broken user settings often cause odd UI glitches. Here’s how to start fresh:

  1. Close CodeLite entirely.
  2. Navigate to C:\Users\<YourUsername>\AppData\Roaming\CodeLite (replace <YourUsername> with your actual Windows login name).
  3. Rename the CodeLite folder to CodeLite_old to back up your existing settings.
  4. Launch CodeLite again—it will generate a clean set of default configurations. Check if text displays properly now.

• Run CodeLite in Compatibility Mode
  Windows 7’s compatibility settings can resolve rendering conflicts with older apps:

  1. Right-click your CodeLite shortcut and select Properties.
  2. Switch to the Compatibility tab.
  3. Check "Run this program in compatibility mode for:" and pick either Windows Vista (Service Pack 2) or Windows XP (Service Pack 3).
  4. Also check "Run this program as an administrator" to rule out permission-related issues.
  5. Click Apply and launch CodeLite to test.

• Check System Font Integrity
  Missing or corrupted system fonts can break text rendering in apps like CodeLite:

  1. Open Control Panel → Fonts.
  2. Verify that common monospaced fonts like Consolas or Courier New are installed. If they’re missing, restore them from a working Windows 7 system or reinstall them manually.
  3. Try resetting your system’s default font settings to ensure custom font tweaks aren’t causing conflicts.

• Test Different CodeLite Versions
  CodeLite 12.0.2 is a 2018 release, so it might have unpatched compatibility issues with your Windows 7 setup. Try installing either a newer version that still supports Windows 7 (like 14.x, available in CodeLite’s official archives) or an older stable release (like 11.x) to see if the problem is version-specific.

Context from Your Screenshots #

Your screenshots confirm that the text rendering engine is failing across multiple UI areas—editor windows, settings previews, and the "Colours and Fonts" panel—while core functionality stays intact. This points to a problem with the UI rendering layer rather than CodeLite’s core code-processing logic.
