Created attachment 860782 [details] dmesg I have a weird bug on my Gentoo system on wlroots compositor (I don't tested in other Wayland compositor). If i have my Nvidia dGPU disable (using supergfxctl to save battery and allow to use the Nvidia card on Windows VM using vfio) and try to open Wayland native apps, the apps just freeze or segfault dsmeg or do both (Hyprland and sway also segfault in the dsmeg but start fine). If its a qt app it freezes and segfault in case of apps the use opengl like alacrity the app just freeze when try to open from other terminal and never opens. The weird thing if i enable Nvidia DGPU even without using (the driver is loaded but the Nvidia GPU is not being using in any app) all the Wayland apps open without a problem. If a force all apps to use XWayland the problem get solve but its not ideal. I will attach my make.conf and dsmeg

Created attachment 860784 [details] Hyprland config
hyprland package: [ebuild R ] gui-wm/hyprland-0.24.1::thegreatmcpain USE="X hwdata seatd source udev vulkan x11-backend" VIDEO_CARDS="nvidia" 0 KiB
gui-wm/hyprland is not a Gentoo package.
@Mike Gilbert i also said it happen in sway (the gentoo package) and the segfaults are mostly the same if you what i can upload the outputs in sway?
A couple of day i found out when I only have the iGPU enable apps that have wayland version seem to freeze and i need to kill the using htop/btop or use the kill command for them to open. Link the video showing the bug:https://youtu.be/3971w_UJ_Og dsmeg when i do the follwing action: ```[21637.217405] gtklock[754489]: segfault at 563df3399b23 ip 00007fa55165d21d sp 00007ffc741842a8 error 4 in libgobject-2.0.so.0.7600.2[7fa551623000+42000] likely on CPU 2 (core 1, socket 0) [21637.217432] Code: 08 48 8d 15 6a 3b 01 00 be 04 00 00 00 48 8d 3d f9 7d 00 00 31 c0 e8 02 63 fc ff eb fe 48 85 ff 74 4b 48 8b 07 48 85 c0 74 43 <48> 8b 00 48 3d fc 03 00 00 76 18 48 83 e0 fc 0f b6 50 14 48 83 7c [22336.395911] xdg-desktop-por[4472]: segfault at 8 ip 00007f9b9f49600b sp 00007ffcece0e1a8 error 6 in libwayland-client.so.0.22.0[7f9b9f494000+7000] likely on CPU 6 (core 3, socket 0) [22336.395932] Code: 89 f6 48 89 df e8 95 f3 ff ff eb ad 0f 1f 00 31 c0 48 39 7f 08 0f 94 c0 c3 66 0f 1f 44 00 00 48 8b 17 48 8b 47 08 c5 f9 ef c0 <48> 89 42 08 48 89 10 c5 fa 7f 07 c3 66 0f 1f 84 00 00 00 00 00 c4 [22397.545960] obs[759772]: segfault at 30 ip 00007fec7014c9a9 sp 00007ffec63740c0 error 4 in libglib-2.0.so.0.7600.2[7fec7009c000+d3000] likely on CPU 6 (core 3, socket 0) [22397.545969] Code: ff 4c 8b 63 18 4d 85 e4 74 1b 48 89 ef e8 6f c1 ff ff 4c 89 e6 48 89 c7 e8 24 0e 01 00 85 c0 0f 84 cc 00 00 00 b8 02 00 00 00 <c4> e2 7b f7 4d 30 0f b6 43 48 89 c2 83 e0 fd d0 ea 83 e2 01 21 ca``

Last nvidia driver (535.86.05) solve the problem and now everthing works as normal with nvidia dgpu disable.
