When switching between tabs or opening new tabs, the tab and the page are not drawn. But if I scroll down the page is drawn.

This doesn't happen always. It happens randomly.

Here's some sample sample images:

I've been having this problem since a few versions back.

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

  • about:config page: layers.offmainthreadcomposition.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

Also make sure that you have the latest updates for your graphics display driver.

layers.offmainthreadcomposition.enabled = false cuased firefox to crash at startup.

Disabling "Use hardware acceleration when available" didn't fix the problem.

Did you try Safe Mode?

In safe mode, there doesn't seem to be any problem. No problems even with hardware acceleration enabled or disabled.

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder in profile folder)
  • default toolbar layout is used
  • JavaScript JIT compilers are disabled
  • hardware acceleration is disabled (Options > Advanced > General)
  • plugins are not affected
  • preferences are not affected
