Rendering Issues with VESA driver

Has a Patch: no Platform: All


Sometimes seems that the screen is not updated correctly, just partially, and some glitches appears. If i move the window application forcing the refresh of the screen the problem disappear. I've tested with a nightly build from 18 June and i couldn't replicate the problem. Also i tested this on a VM and running from the live CD and happened on both cases.

Still an issue? Also, that looks more like an app_server problem than VESA, but I could be wrong.

A really long time passed since i reported this, so i don't remember exactly what i tested. I installed again the last nightly build on VirtualBox and i still encounter some rendering issues. I'm not sure why i said it was a VESA driver issue, but i think that i tested with other driver and that particular issue was not present.

What i can easily see failing one of the things i posted 7 years ago: GL Teapot if i stop the teapot rotation ( stops refreshing the framebuffer ), and i move the mouse over, the mouse rectangle fills the framebuffer with black ( it looks like if the GL framebuffer were the frontbuffer ). Wonderbrush also failed in a similar way but i can't reproduce it again.

I don't think this issue should be still open, i will probably make more sense just to open an issue with the GL Teapot error.
