Summary0036033: Strange mouse behavior
DescriptionWe launch Lazarus. And after a short period of time (not immediately), mysticism begins. After selecting the control, when moving with the mouse (the button is not pressed), a rectangle appears, as if the left button was clamped. This can be seen in the screenshot. If you click on the control again, the selection of the control itself is removed, and the selection rectangle disappears. If you click on another control, both become highlighted. It turns out that you can properly select only in the object inspector.

You mean it happens in designer?
I cannot reproduce here. It may be related to the Linux distro. The desktop in Kubuntu is KDE which I also have with my Manjaro Linux.

This can be reproduced if the controls are located inside the TSrollBox.
