Bug ID: 461029 Summary: [Regression with bisect]: "kwin_core: precision lost! floating value sent to X..." Classification: Plasma Product: kwin Version: 5.26.2 Platform: Compiled Sources OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: core Assignee: kwin-bugs-n...@kde.org Reporter: da...@protonmail.com Target Milestone: --- After updating from Kwin 5.26.1 to 5.26.2 I got the following on the log: kwin_core: precision lost! floating value sent to X 2039.5 kwin_core: precision lost! floating value sent to X 1942.5 kwin_core: precision lost! floating value sent to X 1942.5 kwin_core: precision lost! floating value sent to X 1942.5 kwin_core: precision lost! floating value sent to X 2039.5 At the same time, there's corruption on the screen (the windows were not being repainted when maximized). So I did a bisect and here's the result: da10d8481af24f7ff7092e5a2da5c5262fdd4011 is the first bad commit commit da10d8481af24f7ff7092e5a2da5c5262fdd4011 Author: Arjen Hiemstra <ahiems...@heimr.nl> Date: Mon Oct 24 16:03:52 2022 +0200 Add a helper function to convert QPointF to QPoint using floor instead of round In a bunch of cases, we want to floor when converting to QPoint rather than rounding. As it gets tedious to repeat the same code over and over, add a helper function.

So I downgraded to 5.26.1 and everything is working fine. Thanks! -- You are receiving this mail because: You are watching all bug changes.
