Hi, thank you for your bug report. > 1. Move a window to the screen edge. > 2. RESULT: screen edge doesn't highlight, but it snaps. > 5. On System Settings, change the color theme. > 6. RESULT: screen edges highlights work again, but only till reboot. Could you upload a screen cast demonstrating the issue? The screen edge highlighting is only supposed to work when there is an action configured for the edge. Do you have any actions configured for that edge/is there a hidden panel on that edge? Also are you on wayland or X11? > 3. Move the window elsewhere. > 4. RESULT: the window freezes and crashes, no matter the software. Could you open a separate bug report for this and attach a backtrace? Thanks.
Let me check...

Hi, currently the screen edge highlighting is only supposed to work when there is an action configured for the edge. In your case there are no actions/hidden panels on those edges, so the effect does not show.
I don't mean that highlight. But the one that appears when you want to snap a window into a corner.
And I know it is not intentional because, under unknown circumstances, it does appear!
I have this issue as well since I did a clean install. There is no "preview" of where a window will snap when moving it to the edge of the screen, but sometimes, for unknown reasons it will start to work again. More importantly; sometimes when moving a window to the top edge of the screen, the whole system will freeze and remain so. The only way to unfreeze it, is to do a hard reset (power button).

Sorry, forgot to mention I also found some people having this issue on reddit: https://www.reddit.com/r/kde/comments/1b2djt5/hard_freeze_when_moving_windows_to_edge_of_screen/
Also to add. Setting the snap zones* to "none" doesn't help and it doesn't seem to disable snapping. In fact, it seems to increase the likelihood of the system freezing? *) in Settings > Window Management > Window Behaviour > Movement
I really wish we could edit comments, as I forgot to mention I also have disabled the "maximise windows dragged to top edge", but moving a window to the top edge still gives me snap-behaviour with a(n increased) chance of freezing.
Hi Alberto, I think I get what you are saying in the screencast -- there is no grey "preview" showing you where the window will maximize to. Hi Bert, let's just use this to track the no "preview" issue, and track the freezing issue in BUG: 498544. These two issues might be unrelated because I can easily reproduce the freezing issue, but not the no "preview" issue.

Hi, no problem. As the two issues appeared simultaneously on my system I assumed they were related. Just to confirm what Alberto said: When I change the theme colour (Settings > Colours & Themes > Colours) the preview works again. Next (re)boot it is gone again. It doesn't matter if I use a predefined colour or a custom one, nor does it matter which theme I use.
I just noticed that the preview for the Meta-T areas (shift-move a window) also does not work.
