--- Comment #7 from Holger <h.kl...@gmx.de> --- Created attachment 147870 --> https://bugs.kde.org/attachment.cgi?id=147870&action=edit Screenshot of "transparent" thunderbird Today, I managed a screenshot of Thunderbird. It features a "transparent" area showing the background. And the menubar is moved off it's top position to the middle of the window. It happens on resizing the Thunderbird from windowed to maximized and back. The tranparancy is "true" - moving Thunderbird to a different location, will paint any underlying windows inside Thunderbird. On mouse over of Thunderbird elements, they get redrawn to their supposed location one by one. Workarounds: - Either minimize and restore the window - or drag the border to resize the window - switch Desktop - disable/enable effects by Shift+Alt+F12 Any will immediately fix all drawing issues unless the window is maximized and restored again. The Plasma effect of quickly stretching the window content without explicit redrawing the contents is NOT in use. The Plasma effect of transparent see-through on moving the window is in use. But turning it off, has no impact on this bug. If Plasma-effects are globally off, the former transparent area will be solid black. -- You are receiving this mail because: You are watching all bug changes.
