Before putting anything on the screen, check if the GC was made for the ScreenRec we want to render to. If not, toss the GC and create a new one. This is not the best solution but it does the job for now. Same thing for ARGB cursors except that it's even uglier. Also remember the screen the cursor was rendered to and check for the right screen in the BlockHandler, SourceValidate and a few others. Only remove or restore the cursor if we are rendering to the same screen, otherwise we get artefacts that are both funky and really annoying.
