Tauon tries to create large window and crashes (Arch)

[ViejoRS]

Hello, having a rather odd issue on Arch+KDE+Wayland where Tauon (when installed from the AUR) will crash on launching whether I use Wayland or X11. On Wayland the Tauon window will briefly display, flicker aggressively, and crash out. On X11 Tauon launches in some weirdly huge resolution spanning multiple monitors, and then crashes (often more violently, taking down my DE with it). Under Wayland, I get the following error:

X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  147 ()
  Minor opcode of failed request:  7
  Serial number of failed request:  318
  Current serial number in output stream:  321

If I open Tauon as sudo however in Wayland, it seems to launch fine:

Window size: [1120, 600]

When running in X11, I get a full KDE crash and this is the log:

Application: kded5 (kded5), signal: Segmentation fault

This made me think somehow the bluetooth service was related to the issue (which may also explain why running Tauon as sudo in Wayland works, if it's somehow trying to do some sort of admin access/checking of the bluetooth service?) So I tried stopping and disabling the bluetoot.service to see if there was any impact and got a different error: /usr/bin/tauon: line 13: 3622 Killed python3 /opt/tauon-music-box/tauon.py

Please let me know if any more information would be helpful. I have another laptop with very similar hardware running EndeavourOS+KDE with an X11 default, and Tauon has no issues from the AUR on that machine. On this current laptop I've been working around this issue by running Tauon from Flatpak, which also behaves fine. Love Tauon overall, it's a beautiful program!

I'm not sure. Does seem like it would be video related. I wonder if you have this issue with any other SDL based apps. Hard to investigate unless I was hitting the issue myself.

I wonder if it's something to do with your config, like I wonder if just creating and running as another user makes the problem go away.

By the way there's another option to try, that's running as Wayland native. You can do that using:

SDL_VIDEODRIVER=wayland tauon

Oh actually, if it's trying to create a large window... That might be the issue, try backup and remove tauons data folder. That will give you a fresh Tauon install. The data folder is like in ~/.local/share somewhere.

Wow, thank you this worked. Moving the ~/.local/share/TauonMusicBox to another location and then launching Tauon let it recreate that directory, and now the AUR version of Tauon seems to be running fine.

Super odd because I know I've had this issue since I first installed Arch and Tauon on this computer - as in I never configured anything or changed any settings in Tauon after installing it, just immediately had this bug.

Thank you very much!

Edit: I'm able to get AUR Tauon to launch now but the behavior is still really odd, moving the mini-player between my screens under Wayland will cause Tauon to crash. If I move the window when it's in "full" mode, it doesn't crash but my controls get messed up and I can't interact with the program appropriately (I found that entering mini-player and then going back to full mode lets me use the controls again).

I'll probably play with this a bit more later to see if I can get any other data or messages, but this is ultra-low priority. Thank you very much for your help!
