Brave hard locks on debian when running lxqt desktop. After hard killed, will not start either. This was also reported for Lubuntu here and a few other posts: Brave Browser refuses to launch on Lubuntu 24.04 (LXQt) - #3

How can this issue be reproduced?

  1. apt install brave-browser running fine in GNOME, switch to lxqt.
  2. Set Lxqt Settings → Preferences → Appearance → Widget Style to “gtk2”
  3. Brave instantly hard locks unresponsive and needs to be killed. After killed, will not start until Widget style is set to something else.
  4. Tried in Brave settings to switch between Classic / GTK / Qt etc. no difference locked every time.

Expected result:

Brave not to hard lock. Chromium and FF are both fine.

Additional Information:

Unfortunately I had to uninstall brave-browser due to this bug. A big part of the reason I changed to Lxqt from gnome was because they broke theming with GTK4. Anyway, wanted to at least take the time to file a bugreport since who knows how many others uninstall without taking the effort to at least report what happened.

Thanks for all your work.
