 ## Crashes
 
 - [ ] **MAJOR bug as it prevents testing certain things!** Whenever you build an attraction an assertion error pops up and the game crashes. The shops and stalls are not affected by this problem. [assertion](http://i.imgur.com/ttOLqLB.png?1). Caused by the track previewer (It uses a hack to draw onto a dummy dpi)
-- [x] When switching to the OpenGL rederengine using Intel integrated graphics HD chip which doesn't support OpenGL 3.2 or higher, like the HD3000 on Windows, the game could crash instead of falling back to the software render mode. See #4047, fixed by 664c460.

 - [ ] When saving track design with scenery you see severe graphical corruption. Especially notable if you move over the map.
 - [x] Day and night cycle only affects (certain parts of) the UI or only a part of the gameplay screen gets affected, this changes and so it is not a bug with the exact same symptoms every time. (Seems like it got fixed, need confirmation and further testing)

 - [ ] The dropdown menus from the toolbar have much darker colours.
 - [ ] When it starts raining (rain, heavy rain or thunderstorm), everything, except the UI, turns gray. This changes back to normal after the rain ends.
 - [ ] The water in the lakes is much darker and is not transparent. (It does however animate now, seems like that part got fixed)
-- [x] The water in water attractions like the Log Flume have no animation. (not always reproducible) It seems like it's fixed with #3875, need confirmation.

 - [ ] The selection background color is gray instead of darker red when you hover you mouse over a scenario name at the scenario selection menu.
 - [ ] The background of the Window title at every Window (of the UI, like the options window) gets a gray tint.
 - [ ] Opening the viewport of a ride that uses supports causes severe graphical corruption inside and near the viewport window.
 - [ ] All Abstract Theme objects are not transparent and have a dark colour.
 - [ ] The tiny resize icon at the right bottom of each window has a different color: green/gray
 - [ ] Tab icons at all windows sometimes have a different background color.
