We've just released Pixelmator 3.4.3. This update includes some improvements for stability issues with Pixelmator on certain 2011 Macs that have Intel HD 3000 graphics cards. If you’d like to know more about these issues, we go into more detail here:
In this forum post, we’d like to give you a quick rundown of the changes that we’ve made in this update.
In Pixelmator 3.4.1, we added a workaround that significantly improved performance, although the app would sometimes quit unexpectedly. So, we went back and looked for ways we could improve stability.
With version 3.4.3, we've done just that – Pixelmator should no longer quit unexpectedly when opening images or the app itself. Even when opening images that have a large number of layers.
You may notice that certain things are a bit slower with this version, but this was the only way to improve stability. However, we left a way for you to switch back to how things worked in Pixelmator 3.4.1 and 3.4.2, if you'd like to. Here's how:
1. Quit Pixelmator
2. Open Terminal
(To do that, you can press the Command-Space keyboard shortcut to open Spotlight Search, then start typing "Terminal" and press the Return key when Terminal comes up)
3. Paste "defaults write com.pixelmatorteam.pixelmator PXCEnableOpenCLCPUBlit -bool no" (without quotation marks) into Terminal and hit Return
4. Launch Pixelmator
