I am not sure what do you mean by "work area", but for me (while I am looking at the Xorg-powered display and using lyx), there are problems on almost the whole window. The little animations that should happen when the pointer hovers over the toolbar elements do not happen (the highlighting, maybe that is what it is called), menus do not drop down, and usually even the updates to the main area when the text goes do not happen (so, if I type "aosdiasduioh", the screen stays the same instead of that being shown as typed in. But this is where things turn even weirder ... After I read your question, I wanted to record a video of my screen, with a visible keylogger window, so you guys could see what was happening on my end. It turns out both keylogging and screencasting have an effect on Lyx's perceived window behavior. The most astonishing thing for me is that in the ffmpeg screencasts I made, everything looks totally normal, the recorded Lyx window updates smoothly exactly when it should. In other words, as far as I could tell there is no bug visible from the screencasts, which does NOT correspond to the behavior visible to me while using Lyx. (I will share the screencasts, but they are probably useless.) The other interesting thing was that having a keylogger window (which shows key presses and releases when they happen, see the screencasts) visible alongside the Lyx window caused the Lyx window to show keypress-necessitated window updates that would otherwise be elided. It seems that whenever there was another display update on screen, the Lyx window would also get updated. This might explain why this bug would only become apparent when using Lyx alongside a minimal WM like DWM or without a WM (I usually use Lyx-like applications so they are almost full screen). This leads to an apparent work-around for this bug: one should have, for example, a video player playing a video visible alongside the lyx window.
