I have tested and reproduced in FF 4.0 Beta4, Beta5, Beta6, and Beta7. This does NOT occur in Firefox 3.x. This does not occur also if Firefox is started in safe mode. Reproducible: Always Steps to Reproduce: 1. Install Firefox 4.0 beta 7 on pc. 2. Connect to PC via RDP. 3. Open Firefox. Actual Results: The frame of the Firefox window is visible but the page is completely transparent. You can see the desktop and icons where the page should be. Expected Results: Open firefox to view the page. Running Windows 7 x64 with the newest updates. Have an nvidia geforce 260 graphics card with the newest certified drivers from nvidia installed within the last month. If users connect to a TS and use firefox it will not work at all currently unless you run it in safe mode.
Created attachment 490036 [details] Firefox on initial load in an RDP session This was a screenshot of the issue. Firefox after initial load on an RDP connection.
the safemode disables the hardware acceleration but you can also disable it in the options under advanced. Do you mean bug 594407 ?
Hrm, this does not seem to happen on any of the hardware I've got. This is a known issue.
