Created attachment 128130 [details] Screenshot from Nate who is also affected SUMMARY This is an random issue. Sometimes when Media Player start for the first time Media Player icon is not rendered. I tested with Gwenview - when it is started and not playing icon of Medial Player is sometimes not rendered. This is related to Bug 418662, but not the same. STEPS TO REPRODUCE 1. Do not play anything (no Medial Player icon at all) 2. Run Gwenview 3. Check if Medial Player icon in hidden view is rendered correct. OBSERVED RESULT Sometimes icon is not rendered, looks like invisible or fully transparent. EXPECTED RESULT Icon rendered correctly. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.18 KDE Plasma Version: 5.18.80 KDE Frameworks Version: 5.70.0 Qt Version: 5.14.2
Can reproduce.

Git commit 2ce60f4e502a29e7ce468fc9796fa5088a3486f6 by Konrad Materka. Committed on 25/05/2020 at 22:17. Pushed by kmaterka into branch 'Plasma/5.19'. [applets/systemtray] Lazy initialize SystemTray model Summary: SystemTray model was created in constructor, delay initialization and create it lazily. The `SystemTray::appletAdded` signal is connected to both SystemTray's model and `Container`. `Container` must be connected first, because it sets some properties of newly added applet: `visible` to false and `parent` to the root item (container). If `Container` is connected second, then newly created applet ios added to the model and rendered, but immediately after that `Container` changes visibility to false. Test Plan: 1. Do not play anything (no Medial Player icon at all) 2. Run Gwenview 3. Check if Medial Player icon in hidden view is rendered correct. Before change: Sometimes icon is not rendered, looks like invisible or fully transparent. After change: Icon rendered correctly.
