[kwin] [Bug 487409] LG monitor hotplug on DPMS power on causes several applications to resize their windows
https://bugs.kde.org/show_bug.cgi?id=487409 --- Comment #18 from Christopher Snowhill --- Created attachment 170725 --> https://bugs.kde.org/attachment.cgi?id=170725=edit Screen shot of the messed up Steam announcement window Yeah, this is what the Steam announcement window did in the background. It's ordinarily a non-resizable window. So I guess that may complicate the size restore. Still a little weird that the scale doesn't switch back upon being restored to a 2.0 display, but also weird that the window size shrinks on scale reduction, but doesn't grow on scale growing. -- You are receiving this mail because: You are watching all bug changes.

Steam maintains window positions, but the sizes behave badly. The shrink to 1.0 scale shrinks the window sizes, then they stay 1.0 until I click them again after the restore to the correct output. When I click them, they restore to 2.0 scale, but the window frame size does not double to match the scale change. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=487409 Christopher Snowhill changed: What|Removed |Added Resolution|WAITINGFORINFO |FIXED Status|NEEDSINFO |RESOLVED --- Comment #16 from Christopher Snowhill --- The bug with Xwayland windows seems to be fixed with Plasma 6.1. Steam seems to maintain a consistent sizing and position when the hotplug happens. Wezterm behaves badly, but the bad behavior seems unrelated to this issue, and is probably a different issue. It also behaves really badly when dragged across the edge of the two displays. I'll post a video to the new issue. It may even be a Wezterm issue and not a Plasma issue. It seems their app probably does not like scaling change events. -- You are receiving this mail because: You are watching all bug changes.

With that Xwayland scale change + Steam I managed to reproduce the issue on 6.0.4 and 6.0.5, but I also wrote an autotest and it doesn't happen with the autotest or manual testing on Plasma 6.1. So I'm cautiously optimistic that this bug is already fixed. Please make sure to test with 6.1 as well once that's out. -- You are receiving this mail because: You are watching all bug changes.

This appears to only be happening to Steam now, which is an X11/Xwayland app. When the primary display detaches, the windows migrate to the other display. But then the global Xwayland scale factor automatically changes to the highest scale factor, which is now 1.0. This causes the 3840x2160 virtual surface to compact to 1920x1080 and all the window positions to become cropped to the top left quadrant of the previous surface. It would be nice if the integer scale factor could be configured manually, or retained for longer in the event of a disconnect bounce like this. -- You are receiving this mail because: You are watching all bug changes.

As for the bug report itself, could you give me the output of > kscreen-doctor -o before and after unplugging the screen, and the position and size of any window before it got misplaced? You can get exact coordinates with the kwin debug console (just search for it in krunner). I want to plug those numbers into our autotest, which should've caught issues like this -- You are receiving this mail because: You are watching all bug changes.
