BUG: Graphics corruption in OpenSuSE 13.2 64bit

  • Long time Opera fan here - but sorry that my first post on the Vivaldi forums is a bug report! I was using TP1 without any issues on OpenSuSE 13.2 64bit for a few weeks. Unfortunately when I upgraded to (TP2?) I started to suffer from graphics corruption that renders the browser unusable. The same behaviour has persisted today after I upgraded to (TP3). Chunks of the browser shift around at random like someone's shuffling all the pieces of a jigsaw. Highlighting a paragraph of text (or pressing Ctrl+A) on the webpage being viewed usually clears the problem briefly, but scrolling down the page is sure to bring it back. Ctrl+A will then clear the problem again but.... you get the idea. Using the browser is a constant fight against the graphical corruption and it's not limited to the webpage itself. The tab bar, address bar etc are all affected too. I have attached a png image to illustrate the problem. Is there any more information I can provide in order to help solve this?

    Looks like graphics driver incompatibility. Have you tried disabling GPU rendering in the flags?

  • Thanks for pointing me in the right direction Ayespy - I wasn't aware of vivaldi://flags

    I've been fiddling around with the flags that seem relevant to rendering for the last half hour and based on a little use, I appear to have fixed the problem, although not by disabling GPU rendering…

    The two flags I have had to set to resolve the problem are:
    Enable display list 2D canvas -> ENABLED
    Enable GPU rasterization -> FORCE-ENABLED FOR ALL LAYERS

    And with a restart of vivaldi, the problem is gone.

    If any devs are reading, I'm using an AMD A10-7800 CPU, openSuSE 13.2 with kernel 3.16.7-21-desktop and the FGLRX graphics card drivers (name: fglrx64_core_SUSE132, version: 14.501.1003-2).
