NOTE: I forgot to post 5.1.1 Beta (build 9093) to the blog. See the forum post here for information about the fixes in that build.

This beta build has some more fixes, particular in the way of workarounds for the crash and hang on systems with Sentinel One antivirus.

Change Log

Changes since 5.1.1 Beta (build 9093):

• Fixed the inability to load an image with a bad ICC color profile. The color profile will now be ignored and the image will be treated as if it had an sRGB color profile.
• Fixed the crash in the “anycpu” installer if Sentinel One is installed (“0xc000007b”).
• Fixed the hang at app startup if Sentinel One is installed. If S1 is detected then Async Present will be disabled, which negatively affects input latency/lag (it won’t be worse than PDN 5.0). This is temporary until Sentinel One itself is fixed.
• Fixed (maybe/hopefully) some rendering glitches on some systems. Symptoms include mouse trails and a flickering canvas. This was done by disabling swapchain valid rect propagation, which did not seem to be working anyway. The /disableSwapChainValidRectPropagation command-line parameter has been removed as a result.
• Added the /disableSwapChainPresent1 command-line parameter for troubleshooting purposes (will be removed in a future version).
