Committed on 18/09/2017 at 15:40. Pushed by davidedmundson into branch 'Plasma/5.11'. Don't scale cursor hotspot differently to cursor Summary: In the DRM plugin the cursor is currently is drawn at the native size given. Therefore we don't want to scale the icon offset as that leads to it being drawn every so slightly off-sync. Fixed-in: 5.11.0 Test Plan: Kate now selects lines based on the middle of the cursor, not the top left. I'd previously gotten so used to it, I hadn't realised it was actually a bug :/ Reviewers: #plasma, graesslin Reviewed By: #plasma, graesslin Subscribers: plasma-devel, kwin, #kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D7868 M +1-2plugins/platforms/drm/drm_backend.cpp M +1-1plugins/platforms/drm/drm_output.cpp https://commits.kde.org/kwin/4238218b762996b41480f8d1c9a1c88930e08a11 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384769 David Edmundson changed: What|Removed |Added Status|UNCONFIRMED |CONFIRMED Ever confirmed|0 |1 --- Comment #6 from David Edmundson --- I've made a safe patch for 5.11, that fixes the immediate bug. But I need to revisit this, probably in master. You're right I can extract the source scale, but doing something useful with that is trickier. We have the problem that the dumb buffers are currently shared between the outputs, those outputs might be scaled differently - and we need those buffers in the correct target size. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384769 --- Comment #5 from Martin Flöser --- @David: as the cursor is just a wl_surface: maybe we do get the information of whether it should be scaled as well. If the applications send us a scale on the cursor we could incorporate that in the DRM platform. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384769 --- Comment #4 from David Edmundson --- So the bug is in the DRM hardware cursor rendering, we're not scaling it, but we are implicitly scaling the hotpost. Leading to everything being ever so slighlty off, particularly when you change cursors. The obvious fix is that I should scale the cursor, but then I hit this damn issue again of the user needing different settings depending on whether they're on Wayland or not. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384769 --- Comment #2 from Rainer Finke --- In systemsettings there is a scaling factor of 1x and 2x on Wayland. 2x is applied on my 4k screen automatically. So you first have to apply this, if you don't have scaling enabled yet. Then take a window that is not fullscreen. Either move the mouse pointer to an area where you are able to resize the window or where you are able to close the window with the x in the right corner. You don't have to actually resize or close, it is just about the mouse pointer behaviour itself. Expected result: normal mouse pointer behavior without any strange movements (jumps). Actually the mouse pointer jumps some milimeters like when the border areas are technically the same as what you see on the scren, it doesn't look or feel accurate at all. Without scaling it is fine. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384769 --- Comment #1 from Martin Flöser --- Sorry, but I don't understand what you mean by this. Especially not with closing/resizing windows. Could you please describe in more details what you are doing. Best would be something like: Steps to reproduce: 1. Do this 2. Do that 3. then that Expected behavior: what I expect to happen Actual behavior: What really happens. -- You are receiving this mail because: You are watching all bug changes.
