- Firefox doesn't support transparent menu or corner radius. Related to firefox assuming menus and popups are opaque. Patching firefox can fix the problem, need to figure out whether it can be monkey patched.
- Partially set translucent background crashes amarok (in opengl). (Also affects Oxygen Transparent.) Doesn't crash anymore after doing prepolish, need more tests.
- Transparent dialog break Qt MDI window. Partially fixed by drawing background ourselves. Need to figure out what Oxygen Transparent is doing, what's wrong with preview window (preview window magically looks good now).
- Transparent background make chromium render incorrectly, need to check if Oxygen-gtk's solution (set rgba on a pre-widget bases) works. Setting rgba only on menus should work around the problem.
- Cannot make QMainWindow in Qt5 transparent because of upstream bug. Qt-Bug WORKED AROUND. Need more test
- Menubar in qt does not have translucent background! (NOT True, the problem is double background drawing) Fixed by setting proper composition mode. TODO: need to add a better way to just use parent background. Useful especially when background images are used.
- Remove most application hacks if not all. WIP
- PyQt5, Musescore and (occasionally) QtCreator seg fault on exit in a QtDBus destructor even when QtCurve is not linked to QtDBus.
- QtCurve preference background blur has some problem.
- combobox list background no blur. Fixed by adding the widget to the whitelist, need to figure out whether this is the best way.
- QtQuickControl is a mess... Need improvment on Qt5 side
- Plasma Kickoff (in panel) scrollbar has transparent background... Seems fixed with prepolishing.
- KPartsplugin window does not have styled background. KParsPlugin messes arround with some widget properties and flags Also, different browsers seem to create plugin windows with different depth.
- QMdiSubWindow is filled with solid color when the background is not set to flat. May related to the previous problem (Event Filter?)
