Image shouwing rendering differences

I am attaching a Gitk screen rendered with two different drivers. The Intel driver looks good while the Modesetting driver does not.

intel-force.conf

This is the configuration file I'm using to force intel loading.

I don't know if this bug is the right place to add the following information: there is another rendering difference described in LibreOffice issue # 99705 [1], where the Calc active cell is not rendered when using the modeset driver + OpenGL disabled but it is shown when using the intel driver (or modeset + OpenGL enabled but this broke rendering horribly). Other people confirmed the issue. Some behavior is described there.

It sounds like at least some of the issues you're seeing are due to the Mesa driver.
