v7.2.1 — Linux fixes on Creality Print 7.2.0

Prebuilt Linux AppImage of Creality Print 7.2.0 with Linux-specific fixes applied. Rebased onto Creality's official v7.2.0 release.

Fixes on top of upstream v7.2.0

• Settings/presets are editable again — fixes the read-only filament/process/printer inputs on Linux (issues CrealityOfficial#552, CrealityOfficial#565, CrealityOfficial#576). Root cause: a wxWindowDisabler left the GTK settings dialog insensitive.
• No more crash on exit — static GLModel destructors ran glDeleteBuffers() after the GL context was already torn down, segfaulting on shutdown. Linux now terminates cleanly.
• Breakpad crash handler hardened — dumpCallback no longer throws a boost::filesystem exception out of the signal handler (which previously double-faulted).
• Builds under GCC 13 / Ubuntu 24.04 — fixed two MSVC-only constructs in Creality's new 7.2.0 sources (PrintSettingsPanel.hpp in-class template specialization, Plater.cpp extern-then-static linkage mismatch).
• UI translations bundled — the Linux packaging never compiled the .po files, so the stock build was English-only. This AppImage now ships all 19 locales (ca cs de en es fr hu it ja ko nl pl pt_BR ru sv tr uk zh_CN zh_TW).

Also carries the earlier Linux build fixes (libLerc static link, clean-profile startup crash).

Notes

• Version string reports 7.2.1 (Release). Functionally identical to upstream 7.2.0 plus the fixes above.
• Self-contained AppImage; requires FUSE. chmod +x and run.
• Upstream fix is still pending as PR CrealityOfficial#572.
