Great news.
To fix this issue you have to modify viaSetColorSpace function.
Your chipset ID is PCI_CHIP_VT3259.
Replace following code:
void
viaSetColorSpace(VIAPtr pVia, int hue, int saturation, int brightness,
int contrast, Bool reset)
{
CARD32 col1, col2;
viaCalculateVideoColor(pVia, hue, saturation, brightness, contrast, reset,
&col1, &col2);
switch (pVia->ChipId) {
case PCI_CHIP_VT3205:
case PCI_CHIP_VT3204:
case PCI_CHIP_VT3259:
case PCI_CHIP_VT3314:
VIASETREG(V3_ColorSpaceReg_1, col1);
VIASETREG(V3_ColorSpaceReg_2, col2);
DBG_DD(ErrorF("000002C4 %08lx\n", col1));
DBG_DD(ErrorF("000002C8 %08lx\n", col2));
break;
case PCI_CHIP_VT3327:
case PCI_CHIP_VT3336:
case PCI_CHIP_VT3324:
with:
void
viaSetColorSpace(VIAPtr pVia, int hue, int saturation, int brightness,
int contrast, Bool reset)
{
CARD32 col1, col2;
viaCalculateVideoColor(pVia, hue, saturation, brightness, contrast, reset,
&col1, &col2);
switch (pVia->ChipId) {
case PCI_CHIP_VT3205:
case PCI_CHIP_VT3204:
case PCI_CHIP_VT3314:
VIASETREG(V3_ColorSpaceReg_1, col1);
VIASETREG(V3_ColorSpaceReg_2, col2);
DBG_DD(ErrorF("000002C4 %08lx\n", col1));
DBG_DD(ErrorF("000002C8 %08lx\n", col2));
break;
case PCI_CHIP_VT3259:
case PCI_CHIP_VT3327:
case PCI_CHIP_VT3336:
case PCI_CHIP_VT3324:
