Bug ID: 494193
Summary: Panel popups position broken when
PlasmaCore.Types.NoBackground is applied to the panel
Classification: Plasma
Product: plasmashell
Version: master
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org

dialogs incorrect position on transparent panels
SUMMARY
Making panels fully transparent after "Popups now align with the panel mask"
https://invent.kde.org/plasma/libplasma/-/merge_requests/1148 part of
https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4451 breaks
positioning of popups.
Setting PlasmaCore.Types.NoBackground to the panel containmentItem by using
either https://github.com/sanjay-kr-commit/panelTransparencyToggleForPlasma6 or
https://github.com/luisbocanegra/plasma-panel-colorizer first one recommended
as mine does more things that are unrelated to this issue.
Results in the panel creating an empty mask
https://github.com/KDE/plasma-workspace/blob/c809de7c72dcc7e94eeed5a0b09cb81f5512c2e0/shell/panelview.cpp#L1363C1-L1366C28
```cpp
void PanelView::updateMask()
{
...
if (m_backgroundHints == Plasma::Types::NoBackground) {
KWindowEffects::enableBlurBehind(this, false);
KWindowEffects::enableBackgroundContrast(this, false);
setMask(QRegion()); // <- this line
```
Which successfully removes the blur and contrast (allowing the panel to be
fully transparent) **but breaks the positioning of popups**.
STEPS TO REPRODUCE
1. Install
https://github.com/sanjay-kr-commit/panelTransparencyToggleForPlasma6 KDE Store
url is https://store.kde.org/p/2107649
2. Add it to a panel to make it transparent
3. Expand or hover on widgets
OBSERVED RESULT
Dialogs and tooltips on the left/top of the screen appear over the panel
EXPECTED RESULT
Dialogs and tooltips appear below/next to the panel instead of above it
