看这里写了反复多次检查,看上去意思是之前 LauncherController::instance().currentScreen() 返回的结果可能是个无效的屏幕名称?如果是的话,是不是应该看为什么 LauncherController::instance().currentScreen() 会返回无效的名称?

log: When retrieving wallpaper, the function GetCurrentWorkspaceBackgroundForMonitor was called using only the main screen or an incorrect screen name instead of the screen where the launcher currently resides. If this fails to return a valid result, the wallpaper won't update. Consequently, the appearance service consistently returns the main screen's wallpaper. pms: bug-343521
deepin pr auto review这段代码修改主要是为了优化屏幕选择逻辑,增强代码的健壮性,并添加了更完善的回退机制。以下是对这段 diff 的详细审查意见: 1. 语法与逻辑审查
2. 代码质量审查
3. 代码性能审查
4. 代码安全审查
5. 改进建议虽然这段代码质量已经很高,但仍有以下微小的优化空间:
