First, start by checking your Energy Saver settings. Go to System Preferences > Energy Saver and ensure that the "Put hard disks to sleep when possible" option is unchecked. Sometimes, certain power-saving settings can affect how your Mac behaves when waking from sleep, potentially causing window layout issues.
Next, it's worth resetting the System Management Controller (SMC) on your Mac. The steps to do this can vary depending on the model of your Mac, so I recommend looking up the specific instructions for your Mac model on Apple's support website: Official Apple Support. Resetting the SMC can sometimes help resolve various power-related issues, which could potentially include issues with window layout after waking from sleep.
If the issue persists after checking the Energy Saver settings and resetting the SMC, it's possible that there may be a software bug causing the problem. In this case, it's a good idea to ensure that your Mac is running the latest version of macOS available. Apple frequently releases software updates that include bug fixes and performance improvements, so updating to the latest version of macOS may help resolve the issue.
If none of the above steps resolve the issue, it may be worth reaching out to Official Apple Support directly for further assistance. They can provide more personalized support and guidance based on your specific situation and may be able to offer additional troubleshooting steps or escalate the issue if necessary.
