SUMMARY Some features of VirtualBox 6.0 don't work ("Auto resize guest display" and resize to a specific resolutions) when wayland plasma is picked. STEPS TO REPRODUCE 1. Use virtualbox 6 and install neon-developer-20190514-0001.iso into it, update packages (as of 27may 2019) 2. try to use auto resize guest display feautre 3. OBSERVED RESULT Resizing does not work. EXPECTED RESULT Resizing should work as in Xorg plasma. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.16.80 KDE Frameworks Version: 5.59.0 Qt Version: 5.12.0 Kernel Version: 5.0.0-15-lowlatency OS Type: 64-bit Processor: 1 × Intel® Core™ i7-8550U CPU @ 1.80GHz Memory: 3.9 GiB of RAM
Additional information. Wayland seems to inherit the resolution of sddm size. Whatever size of virtualbox guest window is picked via resizing when sddm login is displayed , this size will get fixed for wayland.
observation: ubuntu(gnome) on wayland works properly with resizing in virtualbox, so it should be doable for plasma on wayland too.
Hi guys, A few more bits from my side. I am observing this issue with Plasma 5.23 on Kubuntu 22.04 guest (VMSVGA graphics configuration). I am using development build of VirtualBox and Additions, but I think with VBox, for example, 6.1.32 (both host and Additions) it is also reproducible. Visually it looks like guest is trying to resize screen, but it does not increase image size. So it is zooming-in a rectangle without increasing its size. Guest screen size can be properly changed via Display Configuration System Settings though. So, issue only occurs when dragging guest's right-bottom corner. We had a small conversation in #kde-kwin channel where I was asked to check if `udevadm monitor` shows `change` events for graphics card when dragging guest's window corner -- events are in place. In addition, when running `konsole` with `WAYLAND_DEBUG=1`, it can be seen that App receives new `wl_output.mode events`: [ 573140.178] wl_output@16.mode(1, 1664, 945, 59999) [ 573140.293] zxdg_output_v1@17.logical_size(1664, 945) [ 573140.327] wl_output@16.done() [ 573187.477] wl_output@16.mode(1, 1666, 947, 59998) [ 573187.615] zxdg_output_v1@17.logical_size(1666, 947) [ 573187.668] wl_output@16.done() [ 573267.788] wl_output@16.mode(1, 1669, 948, 59998) [ 573267.968] zxdg_output_v1@17.logical_size(1669, 948)
I cannot reproduce this issue when using Virtualbox 6.1 and Plasma 5.24 (with and without hardware acceleration) in Fedora KDE spin. If you're still able to reproduce the bug, please reopen the bug report.

Hello Vlad, From my side, I can also confirm that the issue has gone in Kubuntu 22.04.1 with Plasma 5.24.4 (VirtualBox & Guest Additions 6.1.36). Thank you for looking to the issue.
