RSyntaxTextArea
RSyntaxTextArea copied to clipboard
Moving cursor downwards adds height to characters ▀ and █
In an RSyntaxTextArea, set the content to the following:
▀▀▀███
▀▀▀███
▀▀▀███
▀▀▀███
▀▀▀███
▀▀▀███
//etc
Now, move the cursor down; you should see that these characters go up a pixel. There seems to be no effect on the character ▄. I tested with default font and Courier New.
I see the following problem when using the down arrow key to move between those lines - the top row of pixels on the newly-selected line is not rendered I shta twhat you see?
I think you're getting a slightly different bug.
When the cursor is above the characters, I see this:
When it is below, the line goes upwards a pixel:
The bug you're getting only occurs when I use the cursor to move upwards (not downwards):
Note that I'm using a different font to bridge the line gaps between these characters, but the exact same bug occurs with the default font and Courier New.
