Transparent overlay not working with breeze application style (Linux/KDE) #168

OS: Arch Linux DE: KDE freecad version: linkstage3 branch

Problem description: When using breeze application style (kde default), majority of panel (everything except panel titlebar) is not transparent.

Workaround: Panel transparency works as expected, when setting style to fusion in qt5ct and running freecad with "QT_QPA_PLATFORMTHEME=qt5ct freecad". Although the undesired side effect of this is out of place look compared to other applications, as the widget style is different.

Same issue with Adwaita style. UPD: Though it's the Model tab that's opaque. The Tasks tab is actually completely transparent (which is wrong too).

This workaround combined with choosing gradient background (both side of the gradient set the same) and "Use software OpenGL" I was able to have a solid background and use the transparent overlays as per the Vertical UI/UX proposal.

@hellst0rm you really shouldn't need software OpenGL…

@unrelentingtech: I turned that on for fixing a remaining problem I had, which I belive is related to my combination of kde / wayland and the closed source nvidia drivers.

what happend was that when a face on the model was showing transparency it would be transparent throught the freecad window and would show content from the window behind or the desktop wallpaper

I tried with the "use Software openGL" and this solved it temporarily.

oh, #144. Not nvidia related, I've had it on mesa/amd. It somehow stopped being a problem for me at some point, possibly with a LinkDaily update (?)

I have the same issue. Transparent overlay not working with breeze theme -- no difference between native wayland and Xwayland. It seems to work with fusion, ms9x or oxygen theme. Latest AppImage does work. I probably could debug this but I have no idea where to start.
