A fix is needed, not a workaround

🤷 Traied, traied hard and failed. The issue is cause the rendering the surface outside of layer_surface_configure. This can be fixed by setting/checking state->height != 0 in render_frame and layer_surface_configure. The bug is gone, but I hit another issue where only first frame is drawn to the TOP layer, the other one is rendered in normal layer and thus displayed bellow all other windows.

You can check my attempt here (it is a mess, but it seems it fixes the issue) https://github.com/pinkavaj/wshowkeys/tree/pi-fix-wl-err

IMHO the correct fix would be to use even handler for frame rendering, but thats too big change to try ...
