Bugs : lxqt-config package : Ubuntu

My laptop has a native resolution of 2240×1400 (16:10). When I change the resolution to another 16:10 ratio (or any other resolution) like 1920×1200 using LXQT Monitor Settings the screen goes black and comes back at the 2240×1400. Same thing when I change the screen resolution with xrandr.

I am running a fresh install of Lubuntu 23.10 on a Lenova IdeaPad Flex 5 14ALC7 with a AMD Ryzen 7 5700U with integrated graphics.

My choices of resolutions on xrandr are . . .
Screen 0: minimum 320 x 200, current 2240 x 1400, maximum 16384 x 16384
