sometimes when opening a php file - just text view - it will remain white and will not rendere the text . Closing the app and reopening will work but is become annoying

Hi ​@thejudge 

 

Thank you for the detailed information.

I attempted to reproduce the issue on a Windows 11 system using Dreamweaver 21.8, matching the version you reported. I tested with multiple documents open and opened additional PHP, HTML, CSS, and Twig files, but I was unable to reproduce the white-screen rendering behavior. On my test system, documents rendered normally.

Since the issue appears to be intermittent and environment-specific, could you please provide the following information to help us investigate further?

• Does the issue occur with specific files or with any file type?
• Approximately how many documents are open when the problem occurs?
• Are there any external monitors or display scaling settings in use?
• Does the issue persist after resetting Dreamweaver preferences?
• If possible, please share a screen recording showing the behavior when it occurs.

Any additional details or steps that consistently trigger the issue would help us narrow down the root cause.

 

This sounds like a GPU issue. You might try the following:

1. Disable screensavers & other non-essential background processes. 
2. Get the latest drivers from your graphics card maker’s website.
3. Switch to Code/Design view (Ctrl+Shift+F11).  Live takes up more resources.

i want to add that the problem also happens after my computer has activated its screen saver / gone to sleep - then ½ of the open documents will have the white screen that only restarting can solve.
