On another set of experiments, this can no longer be reproduced. So I guess this could have been a coincidence.. 2272803 12 fanzhuyifan 2023-12-10 22:53:41 +0000 This bug seems to be caused by `d->screenGeometry` having an incorrect value at `plasma-workspace/src/libtaskmanager/taskfilterproxymodel.cpp#L358` [1]. To verify this claim, one could add a debug print of `d->screenGeometry`, and note that when the bug triggers, its value is different from any valid screen geometry as reported by `kscreen-doctor -o`. I suspect that this is because when the display configuration changes, the screenGeometry changes value multiple times very quickly (for the snapping and repositioning stuff), causing some sort of race condition and the final change to be missed some how.

It fixes the issue for me on wayland. However, for me dodge windows still doesn't work on X11 (multiple monitors, fractional scaling) 2274893 21 nate 2023-12-18 17:14:40 +0000 This is partially fixed for me on Wayland with multiple monitors now. Rotating a monitor now does the right thing, and a Dodge Windows panel no longer inappropriately un-hides. However I can still reproduce the issue happening when the resolution or scale factor changes. Steps to reproduce: 0. Be on Wayland 1. Have a panel on a screen in Dodge Windows mode 2. Maximize a window so that it hides 3. Go to System Settings > Display & Monitor 4. Increase or decrease the screen's resolution or scale factor *Sometimes* the panel un-hides. Clicking on it and then clicking elsewhere will make it hide again. Other times the panel stays hidden as expected. So overall the behavior feels a bit buggy and glitchy. 2274902 22 fanzhuyifan 2023-12-18 18:04:49 +0000 (In reply to Nate Graham from comment #21) > *Sometimes* the panel un-hides. Clicking on it and then clicking elsewhere > will make it hide again. This sounds like 470760, an existing issue with autohide. Just to clarify, do you still get cases where the panel does not hide even if you click on it and click elsewhere? Previously I was having a lot of cases where the panel does not correctly hide even after I click on it and click elsewhere. 2275404 23 nate 2023-12-20 21:35:42 +0000 I was seeing some of those cases too, yeah. I gather you are as well? Let's use this to track that issue, and Bug 448420 will track the pre-existing issue of panels being un-hidden but hiding again when clicked. 2275409 24 fanzhuyifan 2023-12-20 21:42:32 +0000 (In reply to Nate Graham from comment #23) > I was seeing some of those cases too, yeah.

Humm at least on wayland I haven't seen any cases where the panel shows up and I cannot hide them, even after mouse over/clicks, after edb09185. Do you have more detailed steps to reproduce? X11 seems to be a completely different story though. Last time I checked, on fractional scaling dodge windows doesn't seem to work at all. But since I don't use X11 for my daily drive, I haven't gotten around to taking a closer look yet. 2281984 25 bug-janitor 2024-01-20 18:18:33 +0000 A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/1986 2282102 26 bug-janitor 2024-01-21 10:30:56 +0000 A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/1987 2282105 27 bug-janitor 2024-01-21 10:32:06 +0000 A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/1988 2282106 28 qydwhotmail 2024-01-21 10:39:50 +0000 Git commit ba3995f0859e2fdfe7adb2464867df3b7a1835ec by Fushan Wen, on behalf of Yifan Zhu.

I see it marked as such, but the comment history doesn't seem to indicate the same. Is the following the same problem, or worthy of a new bug? When I connect a new display, the dodging panel fails to dodge until I restart plasmashell. It is not a shared screen edge, because only one monitor is on at a time, so there are no shared edges. I'm not using fractional scaling, but the monitors have different resolutions. X11, Plasma 6.3.3.
