I installed Slickedit on a new Ubuntu 21.10 system, and I'm seeing some weird behavior that only occurs with tool windows. Neither the main window nor the windows of any other apps have this problem. I also didn't have this problem on my other PC running Ubuntu 20.04.
To drag a window, I click and hold the left mouse button while moving the mouse. Normally, the window moves in real time, so when I let go of the mouse button, the window is already there.
Instead, the tool windows don't actually move in real time any more. I move the mouse pointer, but the window stays where it is. When I release the mouse button, the window jumps to the new location. However, I need to move the mouse very slowly in order for the window to actually move all the way. If I move the mouse normally, the window doesn't quite move as much. Usually it only gets half-way there.
I'm sure this is just some dumb setting in Ubuntu and/or Slickedit that I forgot about, but it's really annoying and Google searches don't help.
Update: this problem occurs with a fresh installation of v25 trial, so it's either (another) incompatibility between Slickedit and Linux, or it's some feature of Ubuntu / Gnome / Wayland that's causing problems.
