+++ This bug was initially created as a clone of Bug #1021782 +++ With fvwm-2.6.5-6.fc20.x86_64 and xorg-x11-server-Xorg-1.14.3-4.fc20.x86_64 when a window is moved from location A to B, it is displayed in both A and B in the end. See attached screenshot. --- Additional comment from Peter Lemenkov on 2013-10-22 08:11:54 CEST --- (In reply to Martin Cermak from comment #0) > Created attachment 814856 [details] > screenshot > > With fvwm-2.6.5-6.fc20.x86_64 and xorg-x11-server-Xorg-1.14.3-4.fc20.x86_64 > when a window is moved from location A to B, it is displayed in both A and B > in the end. See attached screenshot. Can't reproduce. I'm using fvwm on a machine with Fedora 20 installed, and never saw this. Perhaps that's some kind of a "tearing" issue (more likely with a proprietary video drivers). I'm using fvwm on F-19 also and didn't see anything like that. Of course some small tearing still exists due to shortcomings of a X11 achitecture but not that magnitude large. --- Additional comment from Martin Cermak on 2013-10-22 08:36:06 CEST --- It's yesterday's fresh install, fedora only repos. --- Additional comment from Martin Cermak on 2013-10-22 08:39:24 CEST --- 07:00.0 VGA compatible controller: NVIDIA Corporation NV44 [Quadro NVS 285] (rev a1) --- Additional comment from Peter Lemenkov on 2013-10-22 08:51:06 CEST --- (In reply to Martin Cermak from comment #3) > 07:00.0 VGA compatible controller: NVIDIA Corporation NV44 [Quadro NVS 285] > (rev a1) Sounds like a driver-related issue then. Could you by any chance replace your card with one from Intel or AMD and retry? --- Additional comment from Martin Cermak on 2013-10-22 10:25:28 CEST --- Worked around using xorg-x11-drv-nvidia-304xx packages. --- Additional comment from Martin Cermak on 2013-10-22 10:41:48 CEST --- Reassigning to xorg-x11-drv-nouveau-1.0.9-2.fc20. Thanks, Peter.
Reproduced this again with 07:00.0 VGA compatible controller: NVIDIA Corporation NV44 [Quadro NVS 285] (rev a1) similarly as in the original bugreport, but newly also with 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) This really looks like a fvwm problem.
Note that other randomly selected window managers work fine with default video drivers on both boxes. This makes fvwm practically unusable.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
