There is no .capx attached because it is not an issue with a single project. I've reproduced it with new AND existing projects. Don't auto-delete this, pretty please?
Steps to reproduce:
1. Install Construct 2 r135
2. Uninstall Construct 2 r135
3. Install Construct 2 r132
4. Start Construct 2 r132
Graphical glitch, see screenshot.
Business as usual.
Internet Explorer: N/A
Operating system & service pack:
Windows 7, Service Pack 1. Updated my graphics drivers, even though it wasn't an issue with any other release of Construct 2.
Edit: Forgot to add my graphics card is a Nvidia Geforce GT 540M (laptop).
Construct 2 version:
After not having used C2 in a while I downloaded the latest beta release. It kept crashing on me (not just the Alt button bug, freezing after a seemingly random amount of time), so I downloaded the latest stable release (r132), uninstalling the beta release in the process. After I ran C2, whatever I did, the graphical glitch keeps showing up. I've tried making new projects (it doesn't show up without a project loaded or created), all with the same result.
If I install r135 (uninstalling r132 in the process), the graphical glitch does not appear, but then I'm stuck with the crashes.
