When I open kwrite and drag on the titlebar to any screen edge, I see the preview for half/quarter screen, however on LMB release the window is not placed accordingly. Instead it is resized in the same position (upper left corner). On second and subsequent drags it is always working. This almost always happens on first try, ~ 98% of the time. Happens also with other apps, konversation, kolourpaint, kate. If needed I can also do a screencast of said behavior. graphics info: $ inxi -G Graphics: Card: Advanced Micro Devices [AMD/ATI] Fiji [Radeon R9 NANO] Display Server: X.Org 1.17.4 driver: amdgpu Resolution: 2560x1440@144hz GLX Renderer: Gallium 0.4 on AMD FIJI (DRM 3.3.0 / 4.8.6-1-CHAKRA, LLVM 3.9.1) GLX Version: 3.0 Mesa 13.0.2

Does it make a difference whether the window is maximized?
(In reply to Martin Flöser from comment #3) > Does it make a difference whether the window is maximized? Yes, if the windows starts up maximized it always seems to work on first try.
Sounds a lot like the regression introduces with 5.9 *** This bug has been marked as a duplicate of bug 376155 ***
