ߚ What's New & Fixed in v2.4

• GDI Cover Art & Focus Interruption Fix

  • Fixed an issue where opening external GUI applications (such as tPad) caused the cover art to disappear due to console clipping region invalidation.
  • RenderCoverArtFast() now validates window clipping regions, automatically recreates memory DCs upon context switches, and re-blits on main loop ticks to ensure artwork never vanishes.
  • Added view-state guarding so cover art only renders on the main screen and no longer bleeds through into the Playlist or Options views.

• Native High-DPI Display Scaling Support

  • Resolved compiler linkage issues with SetProcessDPIAware() by linking user32.ilb.
  • Grid-to-pixel calculations in RenderCoverArtFast() now map 1:1 across 125%, 150%, and 200% display scaling on Windows 10/11 without pixel distortion or blur.

• Zero-Allocation Playlist Search Acceleration

  • Replaced INSTR(LCASE$(...), LCASE$(...)) in FilterPlaylist() with Fletchie's xinstr() using direct string pointers (&fileNameOnly, &cleanQuery).
  • Completely eliminated temporary heap allocations (LCASE$) during search filters, unlocking instant, lag-free search passes over collections of 40,000+ tracks.
