Troubleshooting

• Flickering taskbar after MTA started (desktop mode)
  • Workarround for now, go to settings -> video tab and change resolution to 1280x720 windowed (DO NOT USE FULLSCREEN MODE)

• MTA crashes when entering main menu after selecting fullscreen mode in video settings tab (D3D9.dll crash offset ED711)
  • Manually revert this setting by going to

    /home/deck/.local/share/Steam/steamapps/compatdata/<ID>/pfx/drive_c/Program Files (x86)/MTA San Andreas 1.6/MTA/config

    and opening coreconfig.xml with KWrite application. Search for "display_fullscreen_style" and change the property from 0 to 1.
