## Error While Loading Shared Libraries: libjsoncpp
**Problem:** When you update the `jsoncpp` package, you might get the following error, when trying to run polybar:

## `override-redirect` in i3
**Problem:** i3 and polybar sometimes interact quite weirdly and often `override-redirect = true` is needed to resolve it. This however makes i3 not reserve space for the polybar window, making other windows overlap polybar. There doesn't seem to be that much that we can do about this from polybar's side, because as soon as we need to use `override-redirect = true`, we can't tell i3 to reserve space for the polybar window.
**Workaround:** The workaround that some people use, is to create a full-width fully transparent dummy bar on the same monitor and in the same position (with `override-redirect = false`), so that i3 reserves space for this dummy bar, effectively also reserving space for our actual bar. The real bar may need to have `wm-restack = i3` set for it to not overlap with fullscreen windows. **Note:** This requires that you have a composition manager running because the dummy bar may overlap the real bar.

## KeyError: 'eventstruct'
**Problem:** When building version 3.1.0, during `make` (or `sudo make install`), you may get the following error:
```python
Traceback (most recent call last):
File "/tmp/polybar/lib/xpp/generators/cpp_client.py", line 3163, in <module>
from xcbgen.state import Module
File "/usr/lib/python3.6/site-packages/xcbgen/state.py", line 7, in <module>

out = __main__.output['eventstruct']
KeyError: 'eventstruct'
```
**Fix:** You have to manually update the `xpp` submodule. To do that, go into the `lib/xpp` folder and execute `git checkout master`. After that you can go back into the `build` folder and run `make` again.
