Java Crash: Graphics Driver

Chatty just randomly closes, apparently the JRE completely crashes.

Crash report excerpt

Solution/Workaround

Seems to have to do with the graphics driver. Reinstalling/updating the graphics driver may help or using the following commandline parameter, which should disable the calls to the library that cause the error:

-Dsun.awt.nopixfmt=true

For example:

javaw -Dsun.awt.nopixfmt=true -jar "H:\chatty\Chatty.jar" -cd

Random Errors: Using Calibri Font

After some time, Chatty suddenly shows an error if using the Calibri font.

Solution/Workaround

Hopefully this will be fixed in future Java updates, but for now just don't use a Calibri font.

Twitch Emotes appearing wrong on Retina Displays

Twitch Emoticons appear wrong when Chatty is displayed on a Retina display. Instead of the Emoticon images, the 404 image the Twitch CDN redirects to is shown.

Apparently in newer Java versions Toolkit.getImage() tries to find a higher resolution image by adding @2 to the file name, which the Twitch CDN actually responds to by redirecting to an error image, which is then displayed.

Solution/Workaround

Use Toolkit.createImage() and create an ImageIcon with the created image.
